C Program to add two integers

C Program to Add Two Integers

In this example, we will learn to get two integer as user input then add them and print the output on the screen.

Remainder :

To understand this example, you should have the knowledge of the following C programming topics:

``#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 23The 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);``
