## Overview

This is a small collection of independent C loop exercises, not a single application. Users run individual programs; the pattern examples request a row count and print stars, while the digit-sum example uses a hard-coded number and prints its sum. `while_loop.c` contains several commented-out exercises, but its active program checks whether an entered number is an Armstrong number. The `for_loop.c` entry point is empty. No shared runtime or inter-module calls are evident in the sampled source.

Main entry points: [`while_loop.c`](https://github.com/omprasadk45-prog/c-program/blob/main/while_loop.c) (Armstrong check), [`star pattern.c`](https://github.com/omprasadk45-prog/c-program/blob/main/star%20pattern.c) (Star pattern), [`reverse_star_pattern.c`](https://github.com/omprasadk45-prog/c-program/blob/main/reverse_star_pattern.c) (Reverse stars), [`sum_digits_dowhile.c`](https://github.com/omprasadk45-prog/c-program/blob/main/sum_digits_dowhile.c) (Digit sum)
