What's the difference between a pointer, and a pointer variable?

Question

I know this is very basic but it is little bit confusing to me.
I\'ve read:

a pointer is nothing more than an address

Answer 1

A variable is a place to store a value. In C, whenever you use a variable in a context that needs a value, the value of the variable is retrieved, so saying "p" in that context is the same as saying "the value of variable p":

int *q = p;  // Copy the value of variable p into the variable q.
             // aka: copy p into q.
