## Overview

This repository is a collection of independent C and C++ programming exercises, not a single application. The sampled programs take console input, perform a small calculation or demonstrate a data structure or object-oriented concept, then print results. The graph groups representative exercises by topic; each is a standalone workflow. Source excerpts were available for only a subset of the files, and there is no README, so relationships and capabilities beyond those examples are not inferred.
