## Overview

This tree is a collection of independent C examples, not one application. Their workflows are small: each program runs its own calculation or demonstration and prints results. The `ls.1.c` excerpt appears to be a decompiled directory-listing program; its exact entry-point wiring is not shown, so only its listing role and evident filesystem interaction are represented.

Main entry points: [`sample4.c`](https://github.com/thilaqz/cfiles/blob/main/sample4.c) (Integer calculation), [`sam5.c`](https://github.com/thilaqz/cfiles/blob/main/sam5.c) (Cosine table), [`sam6.c`](https://github.com/thilaqz/cfiles/blob/main/sam6.c) (Ratio calculation), [`sam7.c`](https://github.com/thilaqz/cfiles/blob/main/sam7.c) (Difference ratio)
