Question

Write a program to maintain an inventory for a small used vehicle dealer. The program should maintain and display a list of vehicles,program should also calculate the sales price and monthly payments for a designated vehicle. You will use a class for Vehicle. (Please show proof of the working program. Thank you in advance!)

The class should have data elements for the following information: Lot #, make, model, color, mileage, fuel consumption and list price. You will have the following derived classes from Vehicle: Automobile, Motorcycle. Program will need to have a function to add miles to the mileage; from test drives, or employee use. You only need to update the mileage. You will also need a List class. The List class will use a dynamic array to store Vehicle objects. You will have one list for Automobiles and one for Motorcycles. You will NEVER have an object of class Vehicle.

As each vehicle is entered an object of the appropriate type must be created and added to the correct array. Remember you may need to increase the size of the array. Start each array with 2 elements so the grader can test your resizing. Double the size each time you increase capacity.

Program must perform the following activities: create a list, add items, search for a vehicle, calculate the price and payments for a vehicle, remove a vehicle, and display the inventory. The user should be able to search for any attribute (data member) of the Vehicle, Automobile, or Motorcycle classes. To add an item you should prompt the user to enter the required information. Check the input when adding a vehicle (input validation). This could be easy. Transmissions might be AT, CVT, and MT. The boss definitely doesn’t want negative prices, but also doesn’t want a vehicle sitting because and extra 0 got put in the price. So anything over $10,000 requires an acknowledgement. What else to check?

Program should calculate the final price of the vehicle. We’ll keep things simple. There is only 1 list price. When the user selects a vehicle to purchase you start with the list price, you can deduct any incentives (just entered by the user), add a $95 administrative fee, add any taxes*, deduct the amount of the trade-in (if any), enter an interest rate and loan period to calculate* the monthly payment. Display each of these values to the user. Give them the option to indicate the vehicle sold. If it is sold remove it from the inventory.

The display should show: Menu of choices (display all vehicles in the inventory, adjust mileage for a vehicle, search for a vehicle, add a vehicle, calculate purchase price for a vehicle, and exit. The calculate price option should remove the vehicle if it was sold. The search should display the information for each vehicle matching the criteria.
