Answer :

Pointer operator:- *

It is used to declare a pointer variable. Also used as "value at" operator to read value stored inside the address pointed by pointer.

Example:

int *ptr;

Address operator:-&

It is used to retrieve address of a variable. With address operator address of a variable can be stored in pointer variable.

Example:

int a,*ptr;

ptr=&a;
