COEN 244 Motor Vehicle

A class hierarchy is composed of the following three (3) classes:

  • An abstract base class MotorVehicle,
  • a class Automobile (runs on fuel only), and
  • a class HybridAuto (runs on fuel and batteries).

The class hierarchy has an inheritance structure given by the UML class diagram below see image.

In separate file MotorVehicleHierarchy.cpp provided to you, there are:

  • headers for all classes,
  • nonmember functions printData and printToFile and
  • main function.

Please note the following:

  • MotorVehicleHierarchy.cpp contains the number of points awarded for each correctly implemented function.
  • There are NO syntax errors in file MotorVehicleHierarchy.cpp provided to you. Therefore, you must not change any of the code provided.
  • Changes to given code MotorVehicleHierarchy.cpp will be considered as errors, and marks will be deducted for doing so. In addition, any changes to given code will result in penalties as described in the last page of this exam.
  • Therefore, you must implement all member functions for all classes in the manner described in points (1) and (2) of following two pages, as well as in the comments in MotorVehicleHierarchy.cpp.

(1) Implement all classes so that execution of MotorVehicle Hierarchy.cpp outputs to the screen the following text in green (there are NO blank lines after the first line of text):
