Picture a car dealership. There are many different types of vehicles for sale. The salespeople know every detail about every one. But the accountants inside only care that a vehicle is getting sold. Model this system:

1) The dealer sells Hatchbacks and Sedans

2) These both inherit from Vehicle, and Vehicle cannot have properties. It can have methods, virtual methods, or pure virtual methods.

3) Every vehicle has a price

4) Hatchbacks have 5 doors and sedans have 4

5) Every vehicle has a trunk. A hatchback holds 30 cu ft, a sedan 20

6) Lastly, every vehicle can be started

Make two functions that take a Vehicle pointer as an argument*. Call one Salesperson and the other Accountant. void Salesperson(Vehicle* tWhat); void Accountant(Vehicle* tWhat);

The salesperson function:

1)Prints the type of car

2) Prints how many doors it has

3) Prints the trunk size

4) Starts the car

The Accountant function:

1) Prints the price

PS: If these functions were in a class, they'd be methods. No Sales or Accountant classes.

If you are looking at this in a panic, stop just looking at. You can see there is a Hatchback class and a Sedan class. They have a lot of similarities so they need a base class. Then just start putting things places. If you find you put the same thing in two classes, move it to the parent.

* To do this homework with inheritance but not polymorphism, make two salespeople. SedanSalesman takes a Sedan pointer only, etc.
