Hotel Management System 🍽️🏨

A terminal-based Hotel Management System developed in C++ using Object-Oriented Programming (OOP) concepts and File Handling.

This project simulates a real-world hotel ordering and management system where customers can place orders and administrators can manage inventory, monitor revenue, and track orders.

Built as a college mini project for OOP in C++. Because apparently engineering students must recreate civilization in terminals before being allowed near real software.

🧠 OOP Concepts Used

Concept	Implementation
Encapsulation	Private data members with public getters/setters
Inheritance	User and Admin inherit from Person
Polymorphism	Virtual showRole() function
Abstraction	Abstract base class using pure virtual function
Dynamic Memory	Runtime object allocation using pointers
Exception Handling	Input validation using try/catch

📂 Files Used

main.cpp      -> Complete source code
menu.txt      -> Stores menu items and stock
orders.txt    -> Stores order history and receipts

📋 Menu File Format

Example:

101|Margherita Pizza|250.00|10
102|Veg Burger|120.00|30
103|Pasta Alfredo|180.50|20

Format:

Code | Item Name | Price | Stock

▶️ How to Run

Compile

g++ main.cpp -o hotel

Run

Windows PowerShell

.\hotel

CMD

hotel.exe

🧾 Sample Features Demonstration

Customer Flow

1. View Menu
2. Select Item Code
3. Enter Quantity
4. Make Payment
5. Generate Receipt

---

Admin Flow

1. Login
2. View Stock
3. Update Stock
4. View Orders
5. Check Revenue

---

🔒 Input Validation

The system prevents:

• Invalid numeric input
• Ordering more than available stock
• Negative quantities
• Insufficient payment

---

💾 Data Persistence

The project uses text files to simulate database behavior:

• Menu data persists after program closes
• Orders are stored permanently
• Revenue can be recalculated from order history

---

📈 Future Improvements

Possible enhancements:

• GUI using Qt or SFML
• SQL database integration
• Multi-user networking
• Online ordering support
• Employee management
• Table reservation system

🎯 Project Objective

To demonstrate practical implementation of Object-Oriented Programming concepts through a real-world hotel management simulation system using C++.

---

📌 Conclusion

This project combines OOP principles, file handling, formatted terminal interaction, and role-based system design into a practical management application.

It demonstrates how object-oriented concepts can be applied to solve real-world problems using structured and maintainable C++ code.
