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

The token p is a pointer variable, that points to a variable i. We can simply call it a pointer.

A declaration:

int* p;
int i;
p = &i; 

declares p as the identifier of an int type object. This is usually stated more succinctly as 'p is a pointer to i'. p can be used to refer int variable i after expression p = &i. To access the value of variable i using pointer p you can use the dereference operator * (e.g. *p). And i = 10; equivalent to *p = 10;.

Also, notice in expression p = &i; to read the address of i I used & ampersand operator also called Address of operand.

A pointer is just a logical address (an identifier by which a variable can be referenced). The C standard does not define what a pointer is internally and how it works internally.
