pointer is a mechanism of accessing different memory locations using
the same variable (pointer). Also, pointers is how dynamic memory is
organized: "new" operator returns the address of a dynamic
variable. This address is stored in a pointer. Copy constructor and
overloaded assignment are to preserve the semantics of pass-by-value
and assignment operations respectively.

All this material will be on the final exam.

I discourage looking for answers on the internet: they are often
confusing, inconsistent and occasionally plain wrong. Slides alone are
insufficient for exam preparation. I suggest studying the book then
reviewing the slides and lab assignments. If something is unclear,
please come to my office hours on Monday.

Thanks,
