You are given definitions of an Automobile class and a class Truck derived from Automobile. You are also given a driver program called AutoTest. The driver program creates a Truck and displays information about the truck. Derive another class called Car from the Automobile class. The Car has an attribute called Doors (a 2-door or a 4-door car). We could have made doors an attribute of Automobile. We don’t refer to doors when we talk about Trucks. We mention doors only when we talk about a car. Define constructors and a get method for the Car. Update the AutoTest program to create a Car and display its attributes. 1.
