Question
Write a program in C++ that implements the ADT vehicle (a class with at least one pure virtual function). Information you may want to keep about a vehicle includes
· identification information
· empty weight
· maximum gross weight
· maximum range
· maximum speed
The constructor should take all such information as arguments. Include virtual functions (may be pure or impure) for interrogating each such attribute. Also include a pure virtual function for interrogating the transportation mode.
Construct derived classes airplane, boat, and car each derived directly from vehicle. Each derived class should provide an interrogation function for the transportation mode, which should indicate by-air, by-land, or by-water (or something similar).
Write a short program which instantiates at least one object of each derived type. Verify all operations work correctly.
