RetailPOS_System

A C++ based Point-of-Sale (POS) system for managing product inventory in a convenience store setting. This project was created for an academic course (CSC 2110 - Summer 2025) and demonstrates object-oriented programming concepts such as inheritance, polymorphism, and file I/O.

Features

• Load and manage inventory from a file
• Categorize products (e.g., Soda, Chocolate, Tobacco, LotteryTickets)
• Search products by name, category, or price range
• Add and remove inventory items
• Sell products and calculate total cost
• Handle errors and edge cases (e.g., selling out-of-stock products)
• Apply taxes using inheritance and polymorphism

Technologies Used

• C++
• File I/O
• Inheritance & Polymorphism
• Exception handling
• Object-oriented design

Product Categories

• Tobacco - Includes special tax
• LotteryTickets - Includes both city and county taxes

File Structure

• main.cpp: Menu interface and main driver
• Product.h/cpp: Base class for products
• Tobacco.h/cpp: Derived class with special tax logic
• LotteryTickets.h/cpp: Derived class with dual tax logic
• Inventory.h/cpp: Manages the product list and operations
• Inventory.txt: Sample inventory file

How to Run

1. Open the project in a C++ IDE (Visual Studio recommended)
2. Make sure all .cpp and .h files are included
3. Build and run main.cpp
4. Follow the on-screen menu to test each feature

Example Menu

1. Search Inventory
2. Sell Products
3. Add New Inventory
4. Remove Inventory
5. Exit
