// Sum of Integers (While Loop)
#include <stdio.h>

int main() {
    // Step 1: Declare and initialize variables
    int sum = 0; // Variable to store the sum
    int i = 1;   // Loop counter, initialized to 1

    // Step 2: Use a while loop to iterate from 1 to 10
    // The loop continues as long as i is less than or equal to 10.
    while (i <= 10) {
        sum += i; // Add the current value of i to sum
        i++;      // Increment i for the next iteration
    }

    // Step 3: Print the final sum
    printf("The sum of numbers from 1 to 10 is: %d\n", sum);

    return 0;
