Question

1. Make a Console App (.NET Core) in Visual Studio and name it as A1YourFirstnameLastname.

2. Implement a vehicle rental management system which is capable of doing the following: • View all, available and reserved vehicles. • Reserve vehicle or cancel a reservation.

3. The application must be menu-based app: 1 - View all vehicles 2 - View available vehicles 3 - View reserved vehicles 4 - Reserve a vehicle 5 - Cancel reservation 6 - Exit

4. NOTE: At no point should the application save any information to disk. All information is stored and managed in memory using a collection. The use of collections and the object-oriented design of the solution are an important part of the evaluation of your submission.

5. The rental company has inventory of cars and motorcycles.

• There are three categories of cars: Hatchback, Sedan, SUV

• And three categories of motorcycles: Cruiser, Sports, Dirt

• There are two types of cars: oStandard – a normal car oExotic – expensive sports car

• And two types of motorcycles: oBike – a standard two-wheeler motorcycle oTrike – a three-wheeler motorcycle

6. Create classes to represent Car and Motorcycle.

7. These classes must inherit from parent class Vehicle.

8. These vehicles must have following fields: ID, Name, Rental Price, Category, Type, IsReserved

9. Use your Java and object-oriented programming knowledge to create this hierarchy.

10. The application should keep track of available and reserved vehicles using the most appropriate generic collection.

11. Use LINQ to display all, available and reserved vehicles.

12. Your knowledge of object-oriented programming will play an important role in evaluation. • You will get higher grades if: Proper use of inheritance Interface is user-friendly

Used LINQ to display vehicles

App menu runs smoothly without crashing

Otherwise, there will be grade deductions.

13. The menu should run continuously until the user quits the application.
