## Overview

This small C++ homework program demonstrates dynamic binding for two shape types. The user selects a circle or rectangle and supplies its dimensions; `main.cpp` is intended to create the selected object through a `Shape` pointer and display it. `Shape` defines the abstract interface, while `Circle` and `Rectangle` provide the concrete measurements and display output. The excerpts contain TODOs in the main workflow and class definitions, so those intended connections are supported by the README rather than completed code.

Main entry points: [`main.cpp`](https://github.com/sskeme/eeee346-f26-hw8/blob/main/main.cpp) (Program entry), [`shape.h`](https://github.com/sskeme/eeee346-f26-hw8/blob/main/shape.h) (Circle)
