Arithmetic Operators

Arithmetic Operators | Operators in C | C language

An arithmetic operator performs mathematical operations such as addition, subtraction and multiplication 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)

Example

// C Program to demonstrate the working of arithmetic operators
#include <stdio.h>
int main()
{
    int a = 9,b = 4, c;
    
    c = a+b;
    printf("a+b = %d \n",c);

    c = a-b;
    printf("a-b = %d \n",c);
    
    c = a*b;
    printf("a*b = %d \n",c);
    
    c=a/b;
    printf("a/b = %d \n",c);
    
    c=a%b;
    printf("Remainder when a divided by b = %d \n",c);
    
    return 0;
}

Output

a+b = 13
a-b = 5
a*b = 36
a/b = 2
Remainder when a divided by b=1

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 variables a and b are integers. Hence, the output is also an integer. The compiler neglects the term after 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,

a/b = 2.5  // Because both operands are floating-point variables
a/d = 2.5  // Because one operand is floating-point variable
c/b = 2.5  // Because one operand is floating-point variable
c/d = 2     // Because both operands are integers
