Whenever you print a pointer using "%p", the expression you print should
have the type 'void*'. In all cases in this code, that would require a
cast: (void*). Your code appears to work as expected, because on your
system, as on many others, the conversion to void* is a no-op for these
pointer types. However there are systems where such code won't work as
expected without the cast; it might not work at all, causing your
program to fail.
I didn't notice any other problems with your code, and your description
of what you're expecting to see seems to match the standard (assuming a
linear address space - which is very common, but NOT required).
