Car Rental System

This project is a Car Rental System implemented in C++. It allows users to view available cars, rent a car for a specific number of days, and return a car when finished. Each car has details such as the brand, model, year, and price per day.

2. Rent a Car: Users can rent a car for a specific number of days. The system calculates and displays the total cost based on the daily rental rate.
3. Return a Car: Users can return a car they have rented, making it available again for others to rent.
4. Show All Cars: Displays all cars in the system, including both available and rented cars.
5. Exit: Users can exit the system.
