using namespace std;

int main()

{

int *p,**pp;

int x;

p=&x; //pointer p stores the address of variable x

pp=&p; // double pointer stores the addres of pointer p

cout<<"the address of x is : "<<p<<endl; //prints the address of variable x

cout<<"the address of pointer p is : "<<pp<<endl;//prints the address of pointer p

}

output:

the address of x is : 0x6ffdfc

the address of pointer p is : 0x6ffe00
