Write a C program to input two numbers and perform all arithmetic operations. How to perform all arithmetic operation between two numbers in C programming. C program to find sum, difference, product, quotient and modulus of two given numbers.



First number: 10
Second number: 5


Sum = 15
Difference = 5
Product = 50
Quotient = 2
Modulus = 0

Required knowledge

Fundamentals of C, Data types, Taking user input in C

In my previous post I explained how easily we can find the sum of two numbers. In case you missed here it is -

In this exercise, we will pedal bit more and compute results of all arithmetic operations at once.

Program to perform arithmetic operations

 * C program to perform all arithmetic operations

#include <stdio.h>

int main()
    int num1, num2;
    int sum, sub, mult, mod;
    float div;

     * Read two numbers from user
    printf("Enter any two numbers : ");
    scanf("%d%d", &num1, &num2);

     * Performs all arithmetic operations
    sum = num1 + num2;
    sub = num1 - num2;
    mult = num1 * num2;
    div = (float)num1 / num2;
    mod = num1 % num2;

     * Prints the result of all arithmetic operations
    printf("SUM = %d \n", sum);
    printf("DIFFERENCE = %d \n", sub);
    printf("PRODUCT = %d \n", mult);
    printf("QUOTIENT = %f \n", div);
    printf("MODULUS = %d", mod);

    return 0; 

Note: \n is an escape sequence character used to print new lines (move to the next line).

Enter any two numbers : 20 10
SUM = 30
QUOTIENT = 2.000000

Happy coding ;)
