C Program to Compute Addition Subtraction and Multiplication

The code will ask the user to enter two number digits, and the user will select an operator to execute the addition, subtraction, multiplication, and division of the entered number, and the program will display the result based on the user’s option.

Source code:

#include<stdio.h>
int main()
{
     // declare variables
     int num1, num2, sum, subtract, multiple;

     // inputs from user
     printf("Enter two integers: ");
     scanf("%d %d", &num1, &num2);

     // calculating addition
     sum = num1 + num2;

     // calculating subtraction
     subtract = num1 - num2;

     // calculating multiplocation
     multiple = num1 * num2;

     // print results
     printf("%d + %d = %d\n", num1, num2, sum);
     printf("%d - %d = %d\n", num1, num2, subtract);
     printf("%d * %d = %d\n", num1, num2, multiple);

     return 0;
}

Output:

Enter two integers: 5 10
5 + 10 = 15
5 – 10 = -5
5 * 10 = 50
