In C++ the copy constructor is called implicitly when class objects are returned from a method by return mechanism or when class objects are passed by value to a function. C++ provides a copy constructor if the programmer does not. The default copy constructor ONLY makes member-wise copy or shallow copies. For deep copies an explicit copy constructor that makes deep copies is required. For a class to make deep copies, the three methods below must be provided.
