Calculate sum of two integers

Write a C program that accepts two integers from the user and calculates the sum of the two integers.

Pictorial Presentation:

C Code:

#include <stdio.h>
int main() 
{
    int x, y, sum; // Declare variables for two integers and their sum
    
    // Prompt user for input and store in 'x'
    printf("\nInput the first integer: "); 
    scanf("%d", &x);
    
    // Prompt user for input and store in 'y'
    printf("\nInput the second integer: ");
    scanf("%d", &y);
    
    sum = x + y; // Calculate the sum of 'x' and 'y'
    
    // Print the sum
    printf("\nSum of the above two integers = %d\n", sum);
    
    return 0; // Indicate successful execution
}

Sample Output:

Input the first integer: 25                                            
                                                                       
Input the second integer: 38                                           
                                                                       
Sum of the above two integers = 63
