Consider the inheritance hierarchy shown below. Each part of this question is independent. (a) In which class(es) would it make most sense to have protected members? Which class(es) would be able to access those protected members directly? (b) Which class(es) can access private members of class C directly? (e) Suppose class C contains a pure virtual function. Suppose we wish to instantiate objects of this hierarchy. Which class(es) are or could be abstract and which are concrete? (d) Consider the following list of classes: Car, Steering Wheel, Vehicle, Van, Minivan, AudioSystem, Parking Lot. Your task is to describe all of the is-a and has-a relationships between these classes. Include an inheritance hierarchy for all classes that fit. Fill in the table with is-a or has-a relationship while leaving the cells empty where no relation is applicable.
