What is the difference between pointer and address ?

Answer 1

A pointer is used to store the address of another variable.

try out the following:

int x = 0; // declare variable x
int* y; // declare pointer y
y = &x; // assign address of x to y

& operator in front of variable returns the address of a variable. This address is then stored inside a pointer as shown above.

cout << *y; // outputs 0
cout << y; // outputs address of x

Answer 2

A pointer stores the address of something
example....assume I declared a variable int x=4;
so the program will store x=4 in a memory location, assume it's 543194981646.....this is x's address
now let's create a pointer of x..... int *pnt...pnt =&x
This pointers stores the address of x....

Now let's make this easier...assume you are looking for Bucky's home....so you asked someone and he showed you the location....the person who showed you the location is the pointer and the location is the address of Bucky
I hope it helped :)
