## Overview

This is a command-line restaurant POS and ordering system. Its main workflow loads food and drink records, presents selectable menus, captures item sizes and food instructions, and adds configured items to a bill; bill output includes subtotal, tax, and total, and reset saves a numbered receipt. Food and Drink specialize a shared Billable interface, while Menu and Utils support selection and input validation. The graph reflects the README’s documented capabilities; the sampled source does not show a production application entry point, so initiating interaction is represented as a terminal user.

Main entry points: [`Ordering.cpp`](https://github.com/rektive/restaurantproject/blob/main/Ordering.cpp) (Ordering engine), [`Menu.cpp`](https://github.com/rektive/restaurantproject/blob/main/Menu.cpp) (Interactive menus), [`Food.cpp`](https://github.com/rektive/restaurantproject/blob/main/Food.cpp) (Food items), [`Drink.cpp`](https://github.com/rektive/restaurantproject/blob/main/Drink.cpp) (Drink items)
