Question

write a c++ code for following application You have been hired by XYZ Car Rental to develop a software system for their business.
Your program will have two unordered lists, one of Cars and one of Reservations. 

The Car class will have the following data:
        string plateNumber (this is the key)
        string make
        string model
        enum vehicleType (VehicleType Enumeration of options: sedan, suv, exotic)
        double pricePerDay
        bool isAvailable

        isAvailable should be set to true on initialization, and a public setter method should
        be exposed SetAvailable(bool available); 

Reservation will have the following:
        string name (key)
        string vehicleRented (plate of the car which is our key for the list)


The Program class will be composed of the two lists. 
There will also be a method to display a menu that will have the following options, 
Create a method to process the user's input and call appropriate methods to perform the operation requested.
(Use a switch statement and call the appropriate methods based on the number the user puts in)

    1. List all cars
    2. Add car to inventory
    3. Remove car from inventory
    4. List all reservations
    5. Add a reservations
    6. Cancel reservation
    7. Exit

Option 1: 
    List all the cars in the unordered list of cars
     (Overload the << operator like my example to print each car's info)

Option 2: 
    Prompt for all the information for a vehicle. 
    Create the vehicle and add it to the list of available vehicles

Option 3:
    Remove a vehicle from the list of available cars. 
    If the car is not available (a user has rented it) return an error message and don't remove the vehicle

Option 4: 
    List all the reservations. Use the key in the reservation to retrieve the vehicle details from the list of vehicles

Option 5: 
    Prompt the user for a name. 
    List all the cars that are available (isAvailable=true):
        1. Nissan Sentra (sedan) $24/day
            2. ...
            n+1. Cancel
    
    Prompt the user to enter an option. Your list will need to implement a GetItemAtIndex
    method which will let you select a vehicle based on the menu option. For example if the user selects 1, you would call GetItemAtIndex(choice - 1). 
    Make sure this returns a car reference: Car& GetItemAtIndex(int index) 
    Create a reservation object with this car's plate and the user's name, and call the car's SetAvailable method with  false passed as the argument; 
    If cancel is pressed, show all the original options again

Option 6:
    Propt the user for a name. Remove the reservation object from the list if that user's name is a key. 
    Use the plate number to find the car in the list and set available to true (Make sure the GetItem method returns a reference)

At the end of each option's method (except Exit) make sure ot list the menu options again.
For Exit, quit the program.
