A program to add two numbers takes to numbers and does their mathematical sum and gives it to another variable that stores its sum.
Example Code
#include <stdio.h>
int main(void) {
int a = 545;
int b = 123;
printf("The first number is %d and the second number is %d \n", a , b);
int sum = a + b;
printf("The sum of two numbers is %d" , sum);
return 0;
}Output
The first number is 545 and the second number is 123 The sum of two numbers is 668
