Prompt User to Provide numbers and Add Two numbers in C Language

 Here's an example program in C that prompts the user to provide two numbers and then adds them together:

c
#include <stdio.h>

int main() {
   int num1, num2, sum;

   // prompt user to enter first number
   printf("Enter the first number: ");
   scanf("%d", &num1);

   // prompt user to enter second number
   printf("Enter the second number: ");
   scanf("%d", &num2);

   // add the two numbers together
   sum = num1 + num2;

   // display the result
   printf("The sum of %d and %d is %d.\n", num1, num2, sum);

   return 0;
}

In this program, we declare three integer variables num1, num2, and sum. We then use the printf function to prompt the user to enter the first number and the second number. We use the scanf function to read in the user's input and store it in num1 and num2. We then add the two numbers together and store the result in sum. Finally, we use printf again to display the result to the user.
