Question

We discussed in the class that during the design, you may need a class that serves as an interface for its derived classes, but you would not create any instance of that class. Such a class is called an abstract class. The UML class diagram shown below shows a class hierarchy starting from the Vehicle class which is an abstract class. Write a program to implement this class hierarchy such that the given code in the main function runs without error. 

Vehicle

Bus

Car

Truck

IntraCityBus

InterCityBus

int main() { 

Vehicle* V[] = { 

new Bus, 

new Car, 

new Truck, 

new IntraCityBus, 

new InterCityBus 

}; 

for (int i = 0; i < 5; i++) { 

cout<< V[i]->move() <<endl; 

return 0; 

Your program should produce an output as the following: 

Bus: Moves to carry a large number of people 

Car: Moves to carry a small number of people 

Truck: Moves to transport goods 

Intra-City Bus: Intra-City Bus: Moves to carry a large number of people between two areas of a city 

Inter-City Bus: Inter-City Bus: Moves to carry a large number of people between two cities 

Requirements: 

  • • The names of the classes (Bus, car, etc) in the above output cannot be hard-coded (instead, you may have a data member to store the name) 

 

 

  • • The output shown for IntraCityBus and InterCityBus must be obtained in such a way that their respective move functions must call the parent class function to get the first part of the output and then append the remaining part (e.g., for IntraCityBus, Moves to carry a large number of people” must be returned by the parent function while “between two areas of a city” must be appended by the child
