C program to perform all arithmetic operations

In this program we are going to perform all basic operations like addition, subtraction, multiplication, division, modulus and finding quotient of two numbers.

Example

Input: Enter first number: 20
       Enter second number: 10

Output: Sum = 30
        Difference = 10
        Multiply = 200
        Modulus = 0
        Quotient = 2

C program to perform all arithmetic operations

#include <stdio.h>

void main()
{
    int num1, num2;
    int sum, diff, mul, div, mod, quo;

    printf("Enter first number: ");
    scanf("%d", &num1);
    printf("Enter second number: ");
    scanf("%d", &num2);

    sum = num1 + num2;
    diff = num1 - num2;
    mul = num1 * num2;
    mod = num1 % num2;
    quo = num1 / num2;

    printf("Sum = %d\n", sum);
    printf("Difference = %d\n", diff);
    printf("Multiply = %d\n", mul);
    printf("Modulus = %d\n", mod);
    printf("Quotient = %d\n", quo);
}

Output

Enter first number: 20
Enter second number: 10
Sum = 30
Difference = 10
Multiply = 200
Modulus = 0
Quotient = 2
