C++ programming - open to bidding

Write a C++ program to manage a Car Dealership System. The main user is an employee at the dealership. Build Specifications (35 points) 1. The system should load a catalog of all cars in the inventory, which includes new and old cars. 2. A user can search the inventory: The user of the system can search the inventory by using the make of the car, model of the car, or by category (new or old cars). 3. A user can sell or lease new and old cars. 4. A user can return a leased car into the inventory. 5. Add new and old cars into the inventory. The program must have the following properties (20 points): - You should do error handling (Ex: An employee cannot add a car that already exists) - You should use inheritance, polymorphism, and aggregation. Example: You can design a generic car class, then design derived classes for new and old cars. The car class may have the following data members: VIN (string), Make (string), Model (string), year (integer number), price (floating number), and category (string). The new car class can have warranty provider (string). Old car class can have for example mileage (integer number). Also, design a menu (should still appear until the exit option is chosen) in the Main program that has the following options implemented to test your classes’ functionality (10 points): 1. Search Inventory 2. Sell/Lease cars 3. Return a leased car 4. Add cars to inventory 5. Exit Extra Credit: (10 points) - Save and load data from and to a file. - Show a list of cars within a given price range
