🛠️ Prerequisites

• C++17 compatible compiler
• SQLite3 development library
  • Ubuntu: sudo apt install libsqlite3-dev
• CMake ≥ 3.10

⚙️ Build Instructions

1. Clone the Repository

git clone https://github.com/your-username/vehicle-rental-system.git cd vehicle-rental-system

2. Create the SQLite Database

Run this command to initialize the database with tables and sample data:

sqlite3 data/rental.db < data/rental.sql

3. Build the Project

mkdir build cd build cmake .. make

4. Run the Program

./VehicleRentalSystem ../data/rental.db

🧪 Example Interaction

Enter customer name: Alice

Available vehicles:
Car - Toyota [KA01AB1234], Seats: 5, Rate/hr: 50
Bike - Yamaha [KA02ZX7890], Gear: Yes, Rate/hr: 30
Truck - Tata [KA03TR9988], Load: 12 tons, Rate/hr: 80

Enter vehicle reg number: KA01AB1234
Enter duration in hours: 4
Vehicle rented successfully to Alice!

Return vehicle? (y/n): y
Enter registration number: KA01AB1234
Vehicle KA01AB1234 returned successfully.

✅ To Do
