{
    int ***r, **q, *p, i=8;
    p = &i;
    q = &p;
    r = &q;
    printf("%d, %d, %d\n", *p, **q, ***r);
    return 0;
}
8, 8, 8
4000, 4002, 4004
4000, 4004, 4008

If it declaired that int i,*p then
p= &i (it means p stores the address of i)
*p=value at i
same way
q= &p
**q=value at &i(it means pointer to a integer pointer)
***r= value at &i(it means pointer to a pointer to a poiter )
and it has no limit to extend this pointer to pointer so we can use number of' *'.but all are print only the value so it prints 8,8,8.

Here r contains ***r so it point the i pointer variable.

And q contain the ** pointer variable. And p contain the * pointer variable so it point the i pointer address value.
