Discuss the relative merits of classes and type extensions. Which do you prefer? Why? Building on the outline of Example 10.28, write a program that illustrates the difference between copy constructors and operator= in C++. Your code should include examples of each situation in which one of these may be called (don’t forget parameter passing and function returns). Instrument the copy constructors and assignment operators in each of your classes so that they will print their names when called. Run your program to verify that its behavior matches your expectations.
