## Overview

This repository is a collection of independent solutions to exercises and projects from chapters 2–27 of C Programming: A Modern Approach, not one integrated application. The typical workflow is a learner selecting a chapter program, compiling it as directed, and running it; individual programs then handle their own input and produce output. The map highlights representative inventory, text-processing, and data-structure examples, including the indexed core modules. Most programs were not sampled, so the graph does not infer connections between them.

Main entry points: [`16/projects/04/inventory.c`](https://github.com/williamgherman/c-solutions/blob/master/16/projects/04/inventory.c) (Array inventory), [`17/projects/03/inventory2.c`](https://github.com/williamgherman/c-solutions/blob/master/17/projects/03/inventory2.c) (List inventory), [`22/projects/10/inventory2.c`](https://github.com/williamgherman/c-solutions/blob/master/22/projects/10/inventory2.c) (File inventory), [`15/projects/01/line.c`](https://github.com/williamgherman/c-solutions/blob/master/15/projects/01/line.c) (Text justification)
