⚙️ System Requirements

• GCC / G++ with C++17 support (g++ --version to check)
• Compatible with Windows, Linux, and macOS

---

🚀 Getting Started

Clone the repository

git clone https://github.com/alphaxt/hotel-management-system.git
cd hotel-management-system

Build with Make

make
./build/HotelManagement

Build with CMake

cmake -B build -S .
cmake --build build
./build/HotelManagement

Build manually with g++

g++ -std=c++17 -Iinclude -o build/HotelManagement src/*.cpp
./build/HotelManagement

💡 How It Works

On launch the system presents a menu with options for customer management, room booking, availability checks, billing, and exit. Key behaviours:

• Booking a room updates the room status and creates a linked customer record
• Billing calculates charges based on room type and length of stay, then prints an invoice
• Data persistence — all bookings and customer data are saved to .dat files and reloaded automatically on the next run

---

🎯 Future Enhancements

• Database integration (SQLite) to replace flat-file storage
• Multi-user roles with authentication and access control
• Additional room types, discounts, and promotions
• GUI front-end or web dashboard
