Right syntax to make contents of an array volatile?

I vaguely remember that the order of the volatile keyword has influence on wether you want the pointer to the array to be volatile or the contents itself. If I want the content to be volatile, do I need to write:

volatile short Array[];

or 

short volatile Array[3];

Both of them will work fine. Order of specifiers doesn't matter.

Either will do. It is the difference between

short volatile * ptr; /* pointer to volatile short */

and

short * volatile ptr; /* volatile pointer to short */

that matters.

const behaves the same way.
