Overview

In this tutorial, we will learn about different C Arithmetic Operators
with some examples.

C Arithmetic Operators

 

Arithmetic Operation	Arithmetic Operator	Description	Examples
Addition	+	The addition operator adds the two operands	sum = a + b
Subtraction	–	Subtracts the second operand from the first operand	diff = a – b
Multiplication	*	The multiplication operator multiplies the two operands	product = a * b
Division	/	The division operator divides the numerator by the denominator	div = a/b
Modulus	%	Computes the remainder of the integer division	rem= a%b

Syntax

The general form of the C arithmetic expression is as follows:

<variable_to_store> = operand1 arthOperator operand2 ;

For example, to add two numbers and store the value of the arithmetic
expression to a variable sum:

sum = 10 + 5 ;

To add two variables:

sum = number1 + number2 ;

where sum, number1, and number2 are variables.

    printf ("Difference = %d \n", difference);

    printf ("Product = %d \n", product);

Program Output

Sum = 27
Difference = 17
Product = 110
Division = 4.000000
Modulus = 2
