// Sum of Natural Numbers up to 100 (while loop)
#include <stdio.h>

int main() {
    // Step 1: Declare and initialize variables
    int sum = 0;
    int i = 1; // Starting counter from 1

    // Step 2: Use a while loop to iterate
    while (i <= 100) {
        // Step 3: Add the current number to the sum
        sum += i;

        // Step 4: Increment the counter
        i++;
    }

    // Step 5: Print the final sum
    printf("The sum of natural numbers up to 100 is: %d\n", sum);

    return 0;
