"2. What is a Pointer?
"Pointer is a variable that stores a memory address. OK, that is
simple ! But, what is a memory address then? Every variable is
located under unique location within a computer's memory and this
unique location has its own unique address, the memory address.
Normally, variables hold values such as 5 or "hello" and these
values are stored under specific location within computer memory.
However, pointer is a different beast, because it holds the memory
address as its value and has an ability to "point" ( hence pointer
) to certain value within a memory, by use of its associated memory
"3. Retrieving a Variable's Memory Address
"OK, enough talking and let's get down to the pointer business.
To retrieve a variable's memory address, we need to use address-of
