You probably meant this:

xyz[4][4] abcd;

abcd is contiguous space for 16 xyz values, accessed as a 
two-dimensional array.  I'm not sure what you mean when you talk about 
pointers, but unless xyz is a pointer type, there are not pointers 
involved.  Except that when passed to a function, static arrays are 
passed as the address of the first element.  This is all like in C.

And yes, it's allocated statically, or on the stack.  Unless you put it 
inside a struct, in which case you can allocate it in any way you like, 
as part of a struct instance.

Docs on heap allocating dynamic arrays can be a little tricky to find:
