Overview --Defining a pointer is easy, but you need to know what type of
variable you will be pointing to. For example:
int *Ted; //
The '*' operator defines a pointer
int Beth = Ted; //
Beth equal to Ted ( 1776 )
Beth = * Ted; //
Beth equal to value pointed by
Ted(25)
Ted contains '1776' which is the address in the memory where the
corresponding value, '25', is assigned to Beth.
