xp is of type pointer to int, and you are converting it to the type pointer
to X.  &xp would be the address of xp, and would be of type pointer to
pointer to int.

Here, x is of type X.  &x is the memory address of x, and is of type pointer
to X.  The reinterpret_cast converts that to type pointer to int.
