Arithmetic operators

Arithmetic operators are used to perform basic mathematical calculations.

Example

Addition, subtraction, multiplication, division, modulo operations.

Operator	Description	Example: (a=100,b=10,ans=0)
+	Add to operands	ans = a + b; ans will be 110.
-	Subtract operand_2 form operand_1	ans = a - b; ans will be 90.
*	Multipy two operands	*ans = a b;** ans will be 1000.
/	divides operand_1 by operand_2	ans = a / b; ans will be 10.
%	Gives the remainder after the actual division of operands	ans = a % b; ans will be 0. Because 10 will perfectly divide 100 so remainder will be zero. 8 % 3 = 2. 5 % 4 = 1.

Operator

Description

Example: (a=100,b=10,ans=0)

Add to operands

ans = a + b; ans will be 110.

Subtract operand_2 form operand_1

ans = a - b; ans will be 90.

Multipy two operands

ans = a * b; ans will be 1000.

divides operand_1 by operand_2

ans = a / b; ans will be 10.

Gives the remainder after the actual
division of operands

ans = a % b; ans will be 0.
Because 10 will perfectly divide 100 so remainder will be zero.
8 % 3 = 2.
5 % 4 = 1.

Sample Program

Example

#include<stdio.h>

int main()
{
    int num1 = 100, num2 = 10;

    printf("num1 + num2 = %d\n",num1 + num2);
    printf("num1 - num2 = %d\n",num1 - num2);
    printf("num1 * num2 = %d\n",num1 * num2);
    printf("num1 / num2 = %d\n",num1 / num2);
    printf("num1 %% num2 = %d\n",num1 % num2);

    return 0;
}

To include % in printf, we should use %% symbol.
