C Program to Add Two Integers

Program to Add Two Integers

#include <stdio.h>

int main() {
  int num1, num2, sum;
  printf("Enter two number : ");
  scanf("%d %d", &num1, &num2);
  sum = num1 + num2;
  printf("The sum of %d and %d is %d", num1, num2, sum);
  return 0;
}

Output

Enter two number : 34 23
The sum of 34 and 23 is 57

Working of the above program

• First we declare three integer variables num1, num2 and sum, in which num1, num2 used to store integers and sum to store the sum of both integers .

int num1, num2, sum;

• Then we asked the user to enter two integers.

printf("Enter two number : ");

• Then we take the user input using scanf() function and store the entered value in num1 and num2 variable respectively.

scanf("%d %d", &num1, &num2);

• Then we add num1 and num2 and save the resultant value in variable sum.

sum = num1 + num2;

• Finally, we print the value of num variable using %d format specifier in printf() function.

printf("The sum of %d and %d is %d", num1, num2, sum);
