🚗 Car Rental System in C++

📌 Overview

This project is a simple console-based Car Rental System developed in C++, simulating the features of a real-life car rental service. The system allows users to:

• Sign up and log in
• View available cars and their features
• Book a car for a specified number of days
• Generate invoices
• Manage and add account balance
• View booking history
• Return rented cars

The system is implemented using object-oriented programming (OOP) principles and makes use of basic file handling to store data persistently.

🎯 Features Implemented

• 🔐 User Authentication (Sign Up / Log In)
• 🚘 View car catalog with model, rent price, reviews
• 📅 Select rental days and book a car
• 🧾 Generate invoice/bill for the booking
• 💰 Balance management (add balance, deduct on booking)
• 🕓 View full booking history
• 🔁 Return a car and delete booking from history
• 🗃️ File handling using text files for data persistence

👨‍💻 Skills Applied

• Object-Oriented Programming: Use of classes and objects, encapsulation
• File Handling: Use of fstream for reading/writing files
• CLI Application Design: Menu-driven interface
• Logic Building: Workflow simulation based on real car rental systems
• Debugging and Problem Solving: Identifying and resolving errors during development

📚 What I Learned

• Designing real-life systems using C++
• Structuring a project with multiple responsibilities using OOP
• Storing and retrieving data using file streams
• Building user workflows through logical flowcharts
• Planning and documenting software projects effectively

🛠️ How to Run the Program

1. Clone the repository:

   git clone https://github.com/your-username/car-rental-system-cpp.git

2. Compile the code using a C++ compiler (like g++):

   g++ main.cpp -o car_rental

3. Run the program:

   ./car_rental

🧱 Future Improvements

• Add GUI using libraries like Qt or SFML
• Store data using SQLite or MySQL instead of text files
• Secure login system with encrypted passwords
• Admin panel to manage cars, users, and transactions
• Better error handling and user feedback system
