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

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

    // Step 2: Use a for loop to iterate from 1 to 100
    for (i = 1; i <= 100; i++) {
        // Step 3: Add the current number to the sum
        sum += i; // This is equivalent to sum = sum + i;
    }

    // Step 4: Print the final sum
    printf("The sum of natural numbers up to 100 is: %d\n", sum);

    return 0;
