Dereferencing Pointers

When a pointer is dereferenced, it returns the value that it points to.
The unary (pre-fix) operator * is used to dereference a pointer.
- If pi is a pointer to int, then *pi is the int that pi points to.
Never dereference the null pointer.
Example - Pointers.cpp
Example - ReferenceVariables.cpp
