C Program to Add Two Integers

Program to Add Two Integers

#include <stdio.h>
int main() {    

    int number1, number2, sum;
    
    printf("Enter two integers: ");
    scanf("%d %d", &number1, &number2);

    // calculate the sum
    sum = number1 + number2;      
    
    printf("%d + %d = %d", number1, number2, sum);
    return 0;
}

Output

Enter two integers: 12
11
12 + 11 = 23

In this program, the user is asked to enter two integers. These two integers are stored in variables number1 and number2 respectively.

printf("Enter two integers: ");
scanf("%d %d", &number1, &number2);

Then, these two numbers are added using the + operator, and the result is stored in the sum variable.

sum = number1 + number2;

Finally, the printf() function is used to display the sum of numbers.

printf("%d + %d = %d", number1, number2, sum);
