int (*a)[]; === int x[]; where x is (*a). To work out the other one you
need to know operator precedence, but you need to know operator
precedence to understand a _lot_ of things.

C type _casts_ are slightly harder, since you have to work out where the
identifier belongs in a token sequence that has had it removed. But it's
usually not hard [look for the sequence "*)", which is otherwise illegal
and appears in most complicated type casts].
