Answer to Question #208947 in Programming & Computer Science for Waheed

Question

In traditional way, there are three classes: TRUCK (number, name , NoOfWheel, Price, Capacity, EnginePower, TypeOfConsump), BUS (number, name , NoOfWheel, Price, NoOfSeat, EnginePower, TypeOfConsump, Color, Speed), CAR (number, name , NoOfWheel, Price, NoOfSeat, EnginePower, TypeOfConsump, Color, Speed).

Divide the above three classes into two base classes and three derived classes. Each class will contain two member functions, getdata() to get that class data from user and putdata() to display that class data on the screen
