Barring the small amount of memory used to hold the pointer itself no
memory is allocated for a pointer.  When you define a pointer it will be
pointing to a random area of memory, however if you attempt to read or
write to that area of memory before initializing the pointer you will
most likely end up with a seg fault or worse.
