Challenge 1: 1 Through 10, With a for Loop and a while Loop — Possible Solution
====================================================================

FOR LOOP VERSION:

#include <stdio.h>

int main() {
    for (int i = 1; i <= 10; i++) {
        printf("%d\n", i);
    }
    return 0;
}

WHILE LOOP VERSION (same logic, same output):

#include <stdio.h>

int main() {
    int i = 1;
    while (i <= 10) {
        printf("%d\n", i);
        i++;
    }
    return 0;
}

Both print:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10

WHY THIS WORKS AS AN ANSWER
------------------------------
The while version manually reproduces each of the for loop's three
parts separately -- initialization (int i = 1;) before the loop,
the condition (i <= 10) in the while itself, and the increment (i++)
as the last line inside the body -- demonstrating that a for loop is
really just these three pieces packaged into one line, not a
fundamentally different mechanism.
