In this program we will add two numbers using c programming language. First we will take two variable num1 and num2 to store the value. Then using the arithmetic operator (+) we will add them then we will store the result in sum variable. At last we will print the sum variable to see the result.
/**
* Write a C program to input two numbers from user and calculate
their sum. C program to add two numbers and display their sum as
output. How to add two numbers in C programming.
*/
#include"stdio.h"
int main()
{
int num1, num2, sum;
/*
* Read two numbers from user
*/
printf("Enter first number: ");
scanf("%d", &num1);
printf("Enter second number:");
scanf("%d", &num2);
/* Adding both number is simple and fundamental */
sum = num1 + num2;
/* Prints the sum of two numbers */
printf("Sum of %d and %d = %d \n", num1, num2, sum);
return 0;
}
Enter first number: 55
Enter second number:22
Sum of 55 and 22 = 77

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
