Questions

1. Overload operator= in your Shape exercise from Chapter 8, Mastering Abstract Classes, or alternatively, overload operator= in your ongoing LifeForm/Person/Student classes as follows:

Define operator= in Shape (or LifeForm) and override this method in all of its derived classes. Hint: the derived implementation of operator=() will do more work than its ancestor, yet could call its ancestor’s implementation to perform the base class part of the work.

2. Overload operator<< in your Shape class (or LifeForm class) to print information about each Shape (or LifeForm). The arguments to this function should be an ostream & and a Shape & (or a LifeForm &). Note that ostream is from the C++ Standard Library (using namespace std;).

You may either provide one function, ostream &operator<<(ostream &, Shape &);, and from it call a polymorphic Print(), which is defined in Shape and redefined in each derived class. Or, provide...
