## Overview

This repository is a collection of standalone C and C++ course exercises, not a single application. The typical workflow is that a learner runs one program, enters values through standard input, and reads its calculation or reformatted output. The map groups sampled exercises by week and topic; parallel C/C++ versions are independent implementations. The README describes the course broadly, while the sampled source supports only the specific behaviors shown here.

Main entry points: [`week-01/ex-C.cpp`](https://github.com/briancai666/c-programming-course-2026fall/blob/main/week-01/ex-C.cpp) (Temperature average), [`week-01/ex-B.cpp`](https://github.com/briancai666/c-programming-course-2026fall/blob/main/week-01/ex-B.cpp) (Reorder fields), [`week-02/ex-D.cpp`](https://github.com/briancai666/c-programming-course-2026fall/blob/main/week-02/ex-D.cpp) (Make change), [`week-03/homework/ex-C.cpp`](https://github.com/briancai666/c-programming-course-2026fall/blob/main/week-03/homework/ex-C.cpp) (Make change)
