Question

For Programming Assignment 3 you will be creating a program to manage cars in a dealership. This will again be a menu driven system. The following is your menu: 1. Display Inventory 2. Add a vehicle 3. Update a vehicle 4. Delete a vehicle 5. Sort inventory by VIN 6. Search inventory by Model 7. Read inventory from file 8. Write inventory to file and exit our program will be class based with the following UML representing the classes: Dealer Dealer Name: string Dealer Address: String

Answer 1
