In C programming, assignment operators assign values to variables. Programmers use “=” for this. The left side is a variable, the right side a value or expression.
The “=” operator in C assigns the right value to the left variable. For instance, “x = 5;” sets x as 5.
C also has compound assignment operators like “+=” that combine an operation and assignment. These operators calculate using both sides and assign the result to the left variable.
Knowing assignment operators is crucial for variable manipulation in C programming. Different operators help streamline code and assign values effectively.
Assignment operators in C are used to give values to variables. These operators modify variable values in expressions. C has various assignment operators, such as “=”, “+=”, “-=”, “*=”, “/=”, “%=”, “<<=”, “>>=”, “&=”, “|=”, and “^=”. They help efficiently assign and change values. These operators work with various data types and can do arithmetic and bitwise operations during assignment.
The basic “=” operator in C programming assigns the value on the right to the variable on the left. In an example like int x = 5; , 5 goes to variable x using “=” operator. The variable x then holds the value 5. This operator suits integers, floats, characters, and custom data types but requires matching data types. If not matched, an error occurs. It’s often used to set or change values in programs.
The addition assignment operator “+=” is a compound assignment operator in C programming. It combines the addition operation with the assignment operation. It adds the value on the right side to the current value of the variable on the left side and assigns the result back to the variable on the left side.
For example:
In the above example, the current value of the variable x is 5. The addition assignment operator adds the value 3 to the current value of x, resulting in x being updated to 8.
The addition assignment operator can be used with different data types, such as integers, floats, and characters. It provides a concise way to perform addition and assignment in a single statement. It is particularly useful when updating variables in loops or incrementing/decrementing variables.
The subtraction assignment operator “-=” is a compound assignment operator in C programming . It combines the subtraction operation with the assignment operation. It subtracts the value on the right side from the current value of the variable on the left side and assigns the result back to the variable on the left side.

What is the difference between = and == in c.
The “=” operator is the simple assignment operator in C, used to assign a value to a variable. On the other hand, the “==” operator is the equality operator in C, used to compare two values for equality. While “=” assigns a value to a variable, “==” tests whether two values are equal. For example, “x = 5;” assigns the value 5 to the variable x, while “if (x == 5)” tests whether the value of x is equal to 5.

We have already used the assignment operator ( = ) several times before. Let's discuss it here in detail. The assignment operator ( = ) is used to assign a value to the variable. Its general format is as follows:
The operand on the left side of the assignment operator must be a variable and operand on the right-hand side must be a constant, variable or expression. Here are some examples:
x = 18 // right operand is a constant y = x // right operand is a variable z = 1 * 12 + x // right operand is an expression |
The precedence of the assignment operator is lower than all the operators we have discussed so far and it associates from right to left.
We can also assign the same value to multiple variables at once.
here x , y and z are initialized to 100 .
Since the associativity of the assignment operator ( = ) is from right to left. The above expression is equivalent to the following:
Note that expressions like:
x = 18 y = x z = 1 * 12 + x |
are called assignment expression. If we put a semicolon( ; ) at the end of the expression like this:
x = 18; y = x; z = 1 * 12 + x; |
then the assignment expression becomes assignment statement.
Assignment operations that use the old value of a variable to compute its new value are called Compound Assignment.
Consider the following two statements:
x = 100; x = x + 5; |
Here the second statement adds 5 to the existing value of x . This value is then assigned back to x . Now, the new value of x is 105 .
To handle such operations more succinctly, C provides a special operator called Compound Assignment operator.
The general format of compound assignment operator is as follows:
where op can be any of the arithmetic operators ( + , - , * , / , % ). The above statement is functionally equivalent to the following:
Note : In addition to arithmetic operators, op can also be >> (right shift), << (left shift), | (Bitwise OR), & (Bitwise AND), ^ (Bitwise XOR). We haven't discussed these operators yet.
After evaluating the expression, the op operator is then applied to the result of the expression and the current value of the variable (on the RHS). The result of this operation is then assigned back to the variable (on the LHS). Let's take some examples: The statement:
is equivalent to x = x + 5; or x = x + (5); .
Similarly, the statement:
is equivalent to x = x * 2; or x = x * (2); .
Since, expression on the right side of op operator is evaluated first, the statement:
is equivalent to x = x * (y + 1) .
The precedence of compound assignment operators are same and they associate from right to left (see the precedence table ).
The following table lists some Compound assignment operators:
Operator | Description |
---|---|
equivalent to | |
equivalent to | |
equivalent to | |
equivalent to |
The following program demonstrates Compound assignment operators in action:
#include<stdio.h> int main(void) { int i = 10; char a = 'd'; printf("ASCII value of %c is %d\n", a, a); // print ASCII value of d a += 10; // increment a by 10; printf("ASCII value of %c is %d\n", a, a); // print ASCII value of n a *= 5; // multiple a by 5; printf("a = %d\n", a); a /= 4; // divide a by 4; printf("a = %d\n", a); a %= 2; // remainder of a % 2; printf("a = %d\n", a); a *= a + i; // is equivalent to a = a * (a + i) printf("a = %d\n", a); return 0; // return 0 to operating system } |
Expected Output:
ASCII value of d is 100 ASCII value of n is 110 a = 38 a = 9 a = 1 a = 11 |

Assignment operator in c.
Last Updated on June 23, 2023 by Prepbytes
This type of operator is employed for transforming and assigning values to variables within an operation. In an assignment operation, the right side represents a value, while the left side corresponds to a variable. It is essential that the value on the right side has the same data type as the variable on the left side. If this requirement is not fulfilled, the compiler will issue an error.
In C, the assignment operator serves the purpose of assigning a value to a variable. It is denoted by the equals sign (=) and plays a vital role in storing data within variables for further utilization in code. When using the assignment operator, the value present on the right-hand side is assigned to the variable on the left-hand side. This fundamental operation allows developers to store and manipulate data effectively throughout their programs.
For example, consider the following line of code:
Here is a list of the assignment operators that you can find in the C language:
Simple assignment operator (=): This is the basic assignment operator, which assigns the value on the right-hand side to the variable on the left-hand side.
Addition assignment operator (+=): This operator adds the value on the right-hand side to the variable on the left-hand side and assigns the result back to the variable.
x += 3; // Equivalent to x = x + 3; (adds 3 to the current value of "x" and assigns the result back to "x")
Subtraction assignment operator (-=): This operator subtracts the value on the right-hand side from the variable on the left-hand side and assigns the result back to the variable.
x -= 4; // Equivalent to x = x – 4; (subtracts 4 from the current value of "x" and assigns the result back to "x")
* Multiplication assignment operator ( =):** This operator multiplies the value on the right-hand side with the variable on the left-hand side and assigns the result back to the variable.
x = 2; // Equivalent to x = x 2; (multiplies the current value of "x" by 2 and assigns the result back to "x")
Division assignment operator (/=): This operator divides the variable on the left-hand side by the value on the right-hand side and assigns the result back to the variable.
x /= 2; // Equivalent to x = x / 2; (divides the current value of "x" by 2 and assigns the result back to "x")
Bitwise AND assignment (&=): The bitwise AND assignment operator "&=" performs a bitwise AND operation between the value on the left-hand side and the value on the right-hand side. It then assigns the result back to the left-hand side variable.
x &= 3; // Binary: 0011 // After bitwise AND assignment: x = 1 (Binary: 0001)
Bitwise OR assignment (|=): The bitwise OR assignment operator "|=" performs a bitwise OR operation between the value on the left-hand side and the value on the right-hand side. It then assigns the result back to the left-hand side variable.
x |= 3; // Binary: 0011 // After bitwise OR assignment: x = 7 (Binary: 0111)
Bitwise XOR assignment (^=): The bitwise XOR assignment operator "^=" performs a bitwise XOR operation between the value on the left-hand side and the value on the right-hand side. It then assigns the result back to the left-hand side variable.
x ^= 3; // Binary: 0011 // After bitwise XOR assignment: x = 6 (Binary: 0110)
Left shift assignment (<<=): The left shift assignment operator "<<=" shifts the bits of the value on the left-hand side to the left by the number of positions specified by the value on the right-hand side. It then assigns the result back to the left-hand side variable.
x <<= 2; // Binary: 010100 (Shifted left by 2 positions) // After left shift assignment: x = 20 (Binary: 10100)
Right shift assignment (>>=): The right shift assignment operator ">>=" shifts the bits of the value on the left-hand side to the right by the number of positions specified by the value on the right-hand side. It then assigns the result back to the left-hand side variable.
x >>= 2; // Binary: 101 (Shifted right by 2 positions) // After right shift assignment: x = 5 (Binary: 101)
Conclusion The assignment operator in C, denoted by the equals sign (=), is used to assign a value to a variable. It is a fundamental operation that allows programmers to store data in variables for further use in their code. In addition to the simple assignment operator, C provides compound assignment operators that combine arithmetic or bitwise operations with assignment, allowing for concise and efficient code.
Q1. Can I assign a value of one data type to a variable of another data type? In most cases, assigning a value of one data type to a variable of another data type will result in a warning or error from the compiler. It is generally recommended to assign values of compatible data types to variables.
Q2. What is the difference between the assignment operator (=) and the comparison operator (==)? The assignment operator (=) is used to assign a value to a variable, while the comparison operator (==) is used to check if two values are equal. It is important not to confuse these two operators.
Q3. Can I use multiple assignment operators in a single statement? No, it is not possible to use multiple assignment operators in a single statement. Each assignment operator should be used separately for assigning values to different variables.
Q4. Are there any limitations on the right-hand side value of the assignment operator? The right-hand side value of the assignment operator should be compatible with the data type of the left-hand side variable. If the data types are not compatible, it may lead to unexpected behavior or compiler errors.
Q5. Can I assign the result of an expression to a variable using the assignment operator? Yes, it is possible to assign the result of an expression to a variable using the assignment operator. For example, x = y + z; assigns the sum of y and z to the variable x.
Q6. What happens if I assign a value to an uninitialized variable? Assigning a value to an uninitialized variable will initialize it with the assigned value. However, it is considered good practice to explicitly initialize variables before using them to avoid potential bugs or unintended behavior.

Assignment operators are used to assigning the result of an expression to a variable. Up to now, we have used the shorthand assignment operator “=”, which assigns the result of a right-hand expression to the left-hand variable. For example, in the expression x = y + z, the sum of y and z is assigned to x.
Another form of assignment operator is variable operator_symbol= expression ; which is equivalent to variable = variable operator_symbol expression;
We have the following different types of assignment and assignment short-hand operators.
Expression with an assignment operator | Detailed expression with an assignment operator |
---|---|
x += y; | x = x + y; |
x -= y; | x = x – y; |
x /= y; | x = x / y; |
x *= y; | x = x * y; |
x %= y; | x = x % y; |
x &= y; | x = x & y; |
x |= y; | x = x | y; |
x ^= y; | x = x ^ y; |
x >>= y; | x = x >> y; |
x <<= y; | x = x << y; |

Assignment operator is used to assign value to a variable (memory location). There is a single assignment operator = in C. It evaluates expression on right side of = symbol and assigns evaluated value to left side the variable.
For example consider the below assignment table.
Operation | Description |
---|---|
Assigns 10 to variable | |
Evaluates expression and assign result to | |
Evaluates and assign result to | |
Error, you cannot re-assign a value to a constant | |
Error, you cannot re-assign a value to a constant |
The RHS of assignment operator must be a constant, expression or variable. Whereas LHS must be a variable (valid memory location).
C supports a short variant of assignment operator called compound assignment or shorthand assignment. Shorthand assignment operator combines one of the arithmetic or bitwise operators with assignment operator.
For example, consider following C statements.
The above expression a = a + 2 is equivalent to a += 2 .
Similarly, there are many shorthand assignment operators. Below is a list of shorthand assignment operators in C.
Shorthand assignment operator | Example | Meaning |

An assignment operation assigns the value of the right-hand operand to the storage location named by the left-hand operand. Therefore, the left-hand operand of an assignment operation must be a modifiable l-value. After the assignment, an assignment expression has the value of the left operand but isn't an l-value.
assignment-expression : conditional-expression unary-expression assignment-operator assignment-expression
assignment-operator : one of = *= /= %= += -= <<= >>= &= ^= |=
The assignment operators in C can both transform and assign values in a single operation. C provides the following assignment operators:
Operator | Operation Performed |
---|---|
Simple assignment | |
Multiplication assignment | |
Division assignment | |
Remainder assignment | |
Addition assignment | |
Subtraction assignment | |
Left-shift assignment | |
Right-shift assignment | |
Bitwise-AND assignment | |
Bitwise-exclusive-OR assignment | |
Bitwise-inclusive-OR assignment |
In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place. The left operand must not be an array, a function, or a constant. The specific conversion path, which depends on the two types, is outlined in detail in Type Conversions .

Bitwise Operators in C Programming
An operator is a symbol that operates on a value or a variable. For example: + is an operator to perform addition.
C has a wide range of operators to perform various operations.
An arithmetic operator performs mathematical operations such as addition, subtraction, multiplication, division etc on numerical values (constants and variables).
Operator | Meaning of Operator |
---|---|
+ | addition or unary plus |
- | subtraction or unary minus |
* | multiplication |
/ | division |
% | remainder after division (modulo division) |
The operators + , - and * computes addition, subtraction, and multiplication respectively as you might have expected.
In normal calculation, 9/4 = 2.25 . However, the output is 2 in the program.
It is because both the variables a and b are integers. Hence, the output is also an integer. The compiler neglects the term after the decimal point and shows answer 2 instead of 2.25 .
The modulo operator % computes the remainder. When a=9 is divided by b=4 , the remainder is 1 . The % operator can only be used with integers.
Suppose a = 5.0 , b = 2.0 , c = 5 and d = 2 . Then in C programming,
C programming has two operators increment ++ and decrement -- to change the value of an operand (constant or variable) by 1.
Increment ++ increases the value by 1 whereas decrement -- decreases the value by 1. These two operators are unary operators, meaning they only operate on a single operand.
Here, the operators ++ and -- are used as prefixes. These two operators can also be used as postfixes like a++ and a-- . Visit this page to learn more about how increment and decrement operators work when used as postfix .
An assignment operator is used for assigning a value to a variable. The most common assignment operator is =
Operator | Example | Same as |
---|---|---|
= | a = b | a = b |
+= | a += b | a = a+b |
-= | a -= b | a = a-b |
*= | a *= b | a = a*b |
/= | a /= b | a = a/b |
%= | a %= b | a = a%b |
C relational operators.
A relational operator checks the relationship between two operands. If the relation is true, it returns 1; if the relation is false, it returns value 0.
Relational operators are used in decision making and loops .
Operator | Meaning of Operator | Example |
---|---|---|
== | Equal to | is evaluated to 0 |
> | Greater than | is evaluated to 1 |
< | Less than | is evaluated to 0 |
!= | Not equal to | is evaluated to 1 |
>= | Greater than or equal to | is evaluated to 1 |
<= | Less than or equal to | is evaluated to 0 |
C logical operators.
An expression containing logical operator returns either 0 or 1 depending upon whether expression results true or false. Logical operators are commonly used in decision making in C programming .
Operator | Meaning | Example |
---|---|---|
&& | Logical AND. True only if all operands are true | If c = 5 and d = 2 then, expression equals to 0. |
|| | Logical OR. True only if either one operand is true | If c = 5 and d = 2 then, expression equals to 1. |
! | Logical NOT. True only if the operand is 0 | If c = 5 then, expression equals to 0. |
Explanation of logical operator program
During computation, mathematical operations like: addition, subtraction, multiplication, division, etc are converted to bit-level which makes processing faster and saves power.
Bitwise operators are used in C programming to perform bit-level operations.
Operators | Meaning of operators |
---|---|
& | Bitwise AND |
| | Bitwise OR |
^ | Bitwise exclusive OR |
~ | Bitwise complement |
<< | Shift left |
>> | Shift right |

Comma operator.
Comma operators are used to link related expressions together. For example:
The sizeof is a unary operator that returns the size of data (constants, variables, array, structure, etc).
Other operators such as ternary operator ?: , reference operator & , dereference operator * and member selection operator -> will be discussed in later tutorials.

Operators are used to perform operations on variables and values.
In the example below, we use the + operator to add together two values:
Although the + operator is often used to add together two values, like in the example above, it can also be used to add together a variable and a value, or a variable and another variable:
C divides the operators into the following groups:
Arithmetic operators are used to perform common mathematical operations.
Operator | Name | Description | Example | Try it |
---|---|---|---|---|
+ | Addition | Adds together two values | x + y | |
- | Subtraction | Subtracts one value from another | x - y | |
* | Multiplication | Multiplies two values | x * y | |
/ | Division | Divides one value by another | x / y | |
% | Modulus | Returns the division remainder | x % y | |
++ | Increment | Increases the value of a variable by 1 | ++x | |
-- | Decrement | Decreases the value of a variable by 1 | --x |
Assignment operators are used to assign values to variables.
In the example below, we use the assignment operator ( = ) to assign the value 10 to a variable called x :
The addition assignment operator ( += ) adds a value to a variable:
A list of all assignment operators:
Operator | Example | Same As | Try it |
---|---|---|---|
= | x = 5 | x = 5 | |
+= | x += 3 | x = x + 3 | |
-= | x -= 3 | x = x - 3 | |
*= | x *= 3 | x = x * 3 | |
/= | x /= 3 | x = x / 3 | |
%= | x %= 3 | x = x % 3 | |
&= | x &= 3 | x = x & 3 | |
|= | x |= 3 | x = x | 3 | |
^= | x ^= 3 | x = x ^ 3 | |
>>= | x >>= 3 | x = x >> 3 | |
<<= | x <<= 3 | x = x << 3 |
Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions.
The return value of a comparison is either 1 or 0 , which means true ( 1 ) or false ( 0 ). These values are known as Boolean values , and you will learn more about them in the Booleans and If..Else chapter.
Comparison operators are used to compare two values.
Note: The return value of a comparison is either true ( 1 ) or false ( 0 ).
In the following example, we use the greater than operator ( > ) to find out if 5 is greater than 3:
A list of all comparison operators:
Operator | Name | Example | Description | Try it |
---|---|---|---|---|
== | Equal to | x == y | Returns 1 if the values are equal | |
!= | Not equal | x != y | Returns 1 if the values are not equal | |
> | Greater than | x > y | Returns 1 if the first value is greater than the second value | |
< | Less than | x < y | Returns 1 if the first value is less than the second value | |
>= | Greater than or equal to | x >= y | Returns 1 if the first value is greater than, or equal to, the second value | |
<= | Less than or equal to | x <= y | Returns 1 if the first value is less than, or equal to, the second value |
You can also test for true or false values with logical operators.
Logical operators are used to determine the logic between variables or values, by combining multiple conditions:
Operator | Name | Example | Description | Try it |
---|---|---|---|---|
&& | AND | x < 5 && x < 10 | Returns 1 if both statements are true | |
|| | OR | x < 5 || x < 4 | Returns 1 if one of the statements is true | |
! | NOT | !(x < 5 && x < 10) | Reverse the result, returns 0 if the result is 1 |

Operators are a fundamental part of all the computations that computers perform. Today we will learn about one of them known as Assignment Operators in C. Assignment Operators are used to assign values to variables. The most common assignment operator is = . Assignment Operators are Binary Operators.
Here is a list of the assignment operators that you can find in the C language:
This is the complete list of all assignment operators in C. To read the meaning of operator please keep in mind the above example.
Operator | Meaning Of Operator | Example | Same as |
---|---|---|---|
= | Simple assignment operator | x=y | x=y |
+= | Add left operand to right operand then assign result to left operand | x+=y | x=x+y |

This is the detailed explanation of all the assignment operators in C that we have. Hopefully, This is clear to you.
1. what will be the value of a after the following code is executed.
A) 10 B) 11 C) 12 D) 15
Answer – C. 12 Explanation: a starts at 10, increases by 5 to 15, then decreases by 3 to 12. So, a is 12.
A) 4 B) 8 C) 16 D) 32
Answer: C) 16 Explanation: After right-shifting 8 (binary 1000) by one and then left-shifting the result by two, the value becomes 16 (binary 10000).
Q. How does the /= operator function? Is it a combination of two other operators?
A. The /= operator is a compound assignment operator in C++. It divides the left operand by the right operand and assigns the result to the left operand. It is equivalent to using the / operator and then the = operator separately.
Q. What is the most basic operator among all the assignment operators available in the C language?
A. The most basic assignment operator in the C language is the simple = operator, which is used for assigning a value to a variable.
Assignment operators is a binary operator which is used to assign values in a variable , with its right and left sides being a one-one operand. The operand on the left side is variable in which the value is assigned and the right side operands can contain any of the constant, variable, and expression.
The Assignment operator is a lower priority operator. its priority has much lower than the rest of the other operators. Its priority is more than just the comma operator. The priority of all other operators is more than the assignment operator.
We can assign the same value to multiple variables simultaneously by the assignment operator.
x = y = z = 100
Here x, y, and z are initialized to 100.
In C language, the assignment operator can be divided into two categories.
This operator is used to assign left-side values to the right-side operands, simple assignment operators are represented by (=).
Compound Assignment Operators use the old value of a variable to calculate its new value and reassign the value obtained from the calculation to the same variable.
Examples of compound assignment operators are: (Example: + =, – =, * =, / =,% =, & =, ^ =)
Look at these two statements:
Here in this example, adding 5 to the x variable in the second statement is again being assigned to the x variable.
Compound Assignment Operators provide us with the C language to perform such operation even more effecient and in less time.
Here op can be any arithmetic operators (+, -, *, /,%).
The above statement is equivalent to the following depending on the function:
Let us now know about some important compound assignment operators one by one.
“+ =” -: This operator adds the right operand to the left operand and assigns the output to the left operand.
“- =” -: This operator subtracts the right operand from the left operand and returns the result to the left operand.
“* =” -: This operator multiplies the right operand with the left operand and assigns the result to the left operand.
“/ =” -: This operator splits the left operand with the right operand and assigns the result to the left operand.
“% =” -: This operator takes the modulus using two operands and assigns the result to the left operand.
There are many other assignment operators such as left shift and (<< =) operator, right shift and operator (>> =), bitwise and assignment operator (& =), bitwise OR assignment operator (^ =)
= | sum = 101;101 is assigned to variable sum |
+= | sum += 101; This is same as sum = sum + 101 |
-= | sum -= 101; This is same as sum = sum – 101 |
*= | sum *= 101; This is same as sum = sum * 101 |
/= | sum /= 101; This is same as sum = sum/101 |
%= | sum %= 101; This is same as sum = sum % 101 |
&= | sum&=101; This is same as sum = sum & 101 |
^= | sum ^= 101; This is same as sum = sum ^ 101 |

Using assignment operators, we can assign value to the variables.
Equality sign (=) is used as an assignment operator in C.
Here, value 5 has assigned to the variable var.
Here, value of a has assigned to the variable b . Now, both a and b will hold value 10 .
Basically, the value of right-side operand will be assigned to the left side operand.
Operator | Meaning | Example |

Assignment operators are fundamental in C programming, as they allow you to assign values and manipulate variables efficiently. In this article, we’ll explore the basics of C programming’s assignment operators: = (Assignment), += (Add and assign), -= (Subtract and assign), *= (Multiply and assign), /= (Divide and assign), and %= (Modulus and assign). Through real-world examples and output demonstrations, you’ll gain a solid understanding of how to use these operators effectively in your C programs. Assignment operators are vital tools in C programming, allowing you to manipulate variables and perform calculations efficiently. In this article, we will explore the basic assignment operators (=, +=, -=, *=, /=, and %=) with real-world examples and output demonstrations.
The assignment operator ( = ) is used to assign a value to a variable. It’s the simplest assignment operator. Let’s illustrate this with an example:
The += operator is used to add a value to the current value of a variable and assign the result back to the variable. Here’s an example:
The -= operator is used to subtract a value from the current value of a variable and assign the result back to the variable. Let’s see it in action:
The *= operator is used to multiply the current value of a variable by a value and assign the result back to the variable. Here’s an example:
The /= operator is used to divide the current value of a variable by a value and assign the result back to the variable. Let’s demonstrate it:
The %= operator is used to calculate the modulus of the current value of a variable and a value and assign the result back to the variable. Here’s an example:

Python operators are the symbols that allow us to perform different types of operations on variables and values. They are the building blocks of any programming language, and Python is no exception. Python provides a wide range of operators that can be used to perform arithmetic, logical, comparison, assignment, and bitwise operations.
Understanding the different types of operators is crucial to writing efficient and error-free code in Python. In this section, we will explore the different types of operators available in Python and learn how to use them effectively in our programs. So buckle up and get ready to dive into the world of Python operators!
Arithmetic operators are used in Python to perform basic arithmetic operations such as addition, subtraction, multiplication, division, and more. These operators are used on numeric data types such as integers, floats, and complex numbers.
Python provides the following arithmetic operators:
Operator | Name | Example | Result |
---|---|---|---|
The floor division (//) operator returns the largest integer that is less than or equal to the division result.
Addition is one of the most basic arithmetic operations in Python. It is denoted by the + symbol and is used to add two numbers or concatenate two strings. For example, if we want to add two numbers x and y together, we can use the + operator like this:
Similarly, if we want to concatenate two strings a and b , we can use the + operator like this:
In both cases, the + operator performs the desired operation and returns a new value that we can assign to a variable or use directly.
The subtraction operator (-) is used to subtract one value from another. It takes two operands and returns the difference between them. For example, 5 - 3 will return 2, and 10.5 - 3.2 will return 7.3.
In Python, the subtraction operator can also be used with variables. For example:
Note that the subtraction operator can also be used with negative numbers. For example, 5 - (-3) will return 8.
Multiplication is a mathematical operation that is represented by the symbol * in Python. It is used to find the product of two or more values. Here's an example:
In the above example, we have two variables a and b with values 10 and 5 respectively. We multiply these two variables using the * operator and store the result in the variable c . Finally, we print the value of c which is 50 (the product of a and b ).
In Python, the / operator is used for division. It returns the quotient (result of division) in the form of a float, even if both the operands are integers. If you want to get the quotient as an integer, you can use the // operator, which performs floor division.
Here's an example:
In the example above, we divide a by b using both the / and // operators. The result of the floating point division is stored in c , which is a float, while the result of the integer division is stored in d , which is an integer.
Modulus operator returns the remainder of the division operation between two operands. It is represented by the percentage sign % .
For example, the expression 9 % 4 returns 1 because when 9 is divided by 4, the remainder is 1.
Here is an example code snippet:
Exponentiation is another arithmetic operator in Python represented by the double asterisk symbol (**). It raises the first operand to the power of the second operand.
Here, the base is the first operand, and the exponent is the second operand.
In the above example, 2 is raised to the power of 3, which results in 8.
Floor Division operator in Python is represented by two forward slashes // and it returns the quotient of the division operation rounding down to the nearest integer. For example, the floor division of 7 // 3 would be 2 since 3 goes into 7 two whole times with 1 left over.
Here's an example of using floor division operator:
In the above example, we have defined two variables a and b , and then used floor division operator // to divide a by b . Since a is 10 and b is 3 , the result of a // b is 3 .
Comparison operators, also known as relational operators, are used to compare two values or operands. In Python, comparison operators always return a boolean value - either True or False.
There are six comparison operators in Python:
Equal to (==)
Not equal to (!=)
Greater than (>)
Less than (<)
Greater than or equal to (>=)
Less than or equal to (<=)
These operators are used in conditional statements and loops to test whether a certain condition is true or false.
The equal to operator ( == ) is a comparison operator used to compare the equality of two operands. It returns True if the values of the two operands are equal, otherwise, it returns False .
In this example, the first comparison returns False because x is not equal to y . The second comparison returns True because x is equal to z .
In Python, the "not equal to" operator is represented by the exclamation mark followed by an equal sign (!=). It is a binary operator and is used to compare two values. The operator returns True if the values are not equal and False if they are equal.
Here's an example of using the "not equal to" operator in Python:
The greater than operator ( > ) is used to check if the left operand is greater than the right operand. It returns True if the left operand is greater than the right operand, otherwise, it returns False . Here is an example:
In the example above, x is greater than y , so the expression x > y returns True .
In Python, the less than operator < is used to compare two operands. It returns True if the left operand is less than the right operand, and False otherwise.
In this example, x is less than y , so the if statement evaluates to True , and the first print statement is executed.
The greater than or equal to operator (>=) is used to compare two values. It returns True if the left operand is greater than or equal to the right operand, and False otherwise.
For example:
In this example, the first print statement returns True because x (which is 5) is greater than or equal to y (which is 3). The second print statement returns False because y is less than x .
The "Less than or equal to" operator is represented by the symbol "<=". It is used to check if one value is less than or equal to another value.
For example, in the expression "5 <= 10", the operator "<=" checks if 5 is less than or equal to 10. Since this is true, the expression evaluates to True. However, in the expression "10 <= 5", the operator "<=" checks if 10 is less than or equal to 5. Since this is false, the expression evaluates to False.
Here's an example code snippet demonstrating the use of the "<=" operator:
This code will output "x is less than or equal to y", since 5 is indeed less than or equal to 10.
Python Logical Operators are used to combine two or more conditions and perform logical operations on them. The following are the three logical operators in Python:
These operators are used to perform logical operations on the operands and return a Boolean value.
The 'and' operator returns True if both operands are True, otherwise, it returns False.
The 'or' operator returns True if either of the operands is True, otherwise, it returns False.
The 'not' operator returns the opposite of the operand.
Let's look at depth with some examples to understand how these operators work.
Here's the truth table for the and operator:
Operand 1 | Operand 2 | Result |
---|---|---|
Here's an example code snippet:
In this example, the and operator is used to check if x is smaller than both y and z . If this condition is true, then the statement "x is the smallest number" is printed.
The OR operator in Python is represented by or . It is a logical operator that returns True if at least one of the operands is True , and False otherwise. Here are the possible truth tables for the OR operator:
Operand 1 | Operand 2 | Result |
---|---|---|
Here's an example of using the OR operator in Python:
In this example, x is not greater than y or z , so the output will be x is not greater than y or z .
The NOT operator is a unary operator that negates the value of its operand. In Python, the NOT operator is represented by the keyword "not".
The NOT operator returns True if its operand is False, and vice versa. Here's an example:
In this example, the value of x is True. However, the NOT operator negates the value of x and returns False.
Have you ever wanted to quickly assign or modify a value in Python without writing a lot of code? That's where assignment operators come in handy! They allow you to perform an operation on a variable and assign the result back to the same variable in a single step. In this section, we will explore the different types of assignment operators in Python.
The simple assignment operator in Python is denoted by the equal sign "=" and is used to assign a value to a variable. The syntax for simple assignment is:
where variable is the name of the variable and value is the value to be assigned to the variable.
For example, the following code assigns the value 10 to the variable x :
After executing this code, the variable x will have the value 10 .
Arithmetic assignment operators are a shorthand way of performing arithmetic operations and assignment at the same time. These operators include:
+= : adds the value of the right operand to the value of the left operand and assigns the result to the left operand.
-= : subtracts the value of the right operand from the value of the left operand and assigns the result to the left operand.
*= : multiplies the value of the left operand by the value of the right operand and assigns the result to the left operand.
/= : divides the value of the left operand by the value of the right operand and assigns the result to the left operand.
%= : computes the modulus of the value of the left operand and the value of the right operand, and assigns the result to the left operand.
//= : performs floor division on the value of the left operand and the value of the right operand, and assigns the result to the left operand.
**= : raises the value of the left operand to the power of the value of the right operand, and assigns the result to the left operand.
These operators can be used with numeric values and variables of numeric types, such as integers and floating-point numbers.
In each of the above examples, the arithmetic operation and the assignment operation are performed at the same time using the shorthand arithmetic assignment operator.
Bitwise assignment operators are used to perform a bitwise operation on a variable and then assign the result to the same variable. The bitwise assignment operators include:
&= : Performs a bitwise AND operation on the variable and the value on the right, then assigns the result to the variable.
|= : Performs a bitwise OR operation on the variable and the value on the right, then assigns the result to the variable.
^= : Performs a bitwise XOR operation on the variable and the value on the right, then assigns the result to the variable.
<<= : Performs a left shift operation on the variable by the number of bits specified on the right, then assigns the result to the variable.
>>= : Performs a right shift operation on the variable by the number of bits specified on the right, then assigns the result to the variable.
There are no specific "Logical Assignment Operators" in Python, as the logical operators and , or , and not are already used for combining and negating boolean expressions. However, it is possible to use logical operators in combination with assignment operators to create compound expressions, such as x += y or z , which assigns the value of y to x if y is truthy, or the value of z otherwise.
There is no such thing as "Comparison Assignment Operators". The term "comparison operator" refers to operators that compare two values and return a boolean value (True or False), while "assignment operator" refers to operators that assign a value to a variable.
However, there are shorthand ways to perform a comparison and assign the result to a variable in a single line of code. For example:
x = 10 if a > b else 20 : This assigns the value 10 to x if a > b is True, otherwise it assigns the value 20.
x += 1 if a == b else 2 : This adds 1 to x if a == b is True, otherwise it adds 2.
x *= 2 if a < b else 3 : This multiplies x by 2 if a < b is True, otherwise it multiplies it by 3.
Bitwise operators are used to manipulate the individual bits of binary numbers. In Python, bitwise operators can be applied to integers. The bitwise operators take two operands and operate on them bit by bit to produce a result. There are six bitwise operators in Python: AND, OR, XOR, NOT, left shift, and right shift. These operators are commonly used in low-level programming, such as device driver development and network packet processing.
The bitwise AND operator is represented by the & symbol in Python. It performs a logical AND operation on each corresponding bit of its operands. If both bits are 1, the resulting bit is 1. Otherwise, the resulting bit is 0.
In this example, a and b are two integers represented in binary. The & operator is used to perform a bitwise AND operation on the two numbers, resulting in the binary number 0010 , which is equivalent to the decimal number 2. The resulting value is assigned to the variable c .
Bitwise OR is another binary operator that operates on two integers and performs a bitwise OR operation on their binary representations. The resulting binary representation is converted back to an integer.
The syntax for the bitwise OR operator is the pipe symbol | . For example, a | b performs a bitwise OR operation on a and b .
In the above example, the binary OR operation on a and b results in 0011 1101 , which is equal to 61 in decimal representation.
Bitwise XOR (exclusive OR) operator is represented by the symbol ^ in Python. The operator returns a binary number that has a 1 in each bit position where the corresponding bits of either but not both operands are 1.
For example, let's say we have two variables a = 13 and b = 17 . The binary representation of 13 is 1101 and the binary representation of 17 is 10001 . Now, let's perform the bitwise XOR operation on these two variables:
In the above example, the resulting binary number is 11000 , which is equivalent to the decimal number 24 . Therefore, the value of the variable c will be 24 .
Here is another example that demonstrates the use of bitwise XOR:
In this example, we first define a and b as binary numbers using the 0b prefix. We then perform the bitwise XOR operation on these two numbers and store the result in c . The resulting binary number is 0b110 , which is equivalent to the decimal number 6 . Therefore, the value of the variable c will be 6 .
Bitwise NOT is a unary operator in Python that flips the bits of a number. It is represented by the tilde (~) symbol. When applied to a binary number, the Bitwise NOT operator returns the complement of the number.
In the above code, the value of x is 7, which is represented in binary as 0000 0111. When we apply the Bitwise NOT operator (~) to x , it flips all the bits of the number, resulting in 1111 1000. The output is in two's complement form, which is the way negative numbers are represented in binary.
Membership operators are used to test if a sequence is present in an object. In Python, we have two membership operators:
in : Evaluates to True if the sequence is present in the object.
not in : Evaluates to True if the sequence is not present in the object.
These operators are typically used with strings, lists, tuples, and sets to check if a certain element or a sequence of elements is present in them.
Identity Operators are used to compare the memory locations of two objects. There are two identity operators in Python:
is - Returns True if both variables are the same object.
is not - Returns True if both variables are not the same object.
In this example, x and y have the same values, but they are not the same object. z is assigned the same memory location as x , so x and z are the same object. The is operator returns True when comparing x and z , but False when comparing x and y . The is not operator returns False when comparing x and z , but True when comparing x and y .

What are Assignment Operators? Assignment operators are used in programming to assign values to variables. We use an assignment operator to store and update data within a program. They enable programmers to store data in variables and manipulate that data. The most common assignment operator is the equals sign (=), which assigns the value on the right side of the operator to the variable on ...
The Assignment operators in C are some of the Programming operators that are useful for assigning the values to the declared variables. Equals (=) operator is the most commonly used assignment operator.
Assignment performs implicit conversion from the value of rhs to the type of lhs and then replaces the value in the object designated by lhs with the converted value of rhs . Assignment also returns the same value as what was stored in lhs (so that expressions such as a = b = c are possible). The value category of the assignment operator is non ...
Assignment Operators in C with Examples Last Updated: September 7, 2022 by Chaitanya Singh | Filed Under: c-programming Assignment operators are used to assign value to a variable. The left side of an assignment operator is a variable and on the right side, there is a value, variable, or an expression.
Assignment Operators in C are used to assign values to the variables. The left side operand is called a variable and the right side operand is the value. The value on the right side of the "=" is assigned to the variable on the left side of "=". In this C tutorial, we'll understand the types of C programming assignment operators with examples.
Key Highlights. Assignment operators are used to assign values to variables in C programming.; The simple assignment operator "=" assigns a value on the side to the variable on the left side. Compound operators like "+=" and "-=" perform operation and then assign the result the variable.
The assignment operator ( = ) is used to assign a value to the variable. Its general format is as follows: variable = right_side. The operand on the left side of the assignment operator must be a variable and operand on the right-hand side must be a constant, variable or expression. Here are some examples:
The assignment operator in C, denoted by the equals sign (=), is used to assign a value to a variable. It is a fundamental operation that allows programmers to store data in variables for further use in their code. In addition to the simple assignment operator, C provides compound assignment operators that combine arithmetic or bitwise operations with assignment, allowing for concise and ...
Assignment operators are used to assigning the result of an expression to a variable. Up to now, we have used the shorthand assignment operator "=", which assigns the result of a right-hand expression to the left-hand variable. For example, in the expression x = y + z, the sum of y and z is assigned to x.
Assignment and shorthand assignment operator in C. Assignment operator is used to assign value to a variable (memory location). There is a single assignment operator = in C. It evaluates expression on right side of = symbol and assigns evaluated value to left side the variable. For example consider the below assignment table.
The assignment operators in C can both transform and assign values in a single operation. C provides the following assignment operators: | =. In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place.
In this C Programming Video Tutorial we will learn about assignment operators in detail. Operators are the symbol which will perform different operation on the operands.
An operator is a symbol that operates on a value or a variable. For example: + is an operator to perform addition. In this tutorial, you will learn about different C operators such as arithmetic, increment, assignment, relational, logical, etc. with the help of examples.
Assignment Operators Assignment operators are used to assign values to variables. In the example below, we use the assignment operator ( =) to assign the value 10 to a variable called x:
