"Big Three" Functions

• When a new class uses pointers to allocate memory out of the dynamic storage pool and we use the default C++ behavior for copying, assignment, and no-destruction; some bad things can happen---namely:  aliasing and memory leaks.

• For this reason, whenever you need to manage dynamic storage, you probably also need:

  • A custom-defined copy constructor,

  • A custom-defined assignment operator, and

  • A custom-defined destructor.

• The following stringMutator code provides an example:  simple_class_w_big_three.cpp
