True, but additionally, *depending* on A[10]=0 setting N to 0 as a side-
effect is not reliable. C won't trap that as an error, but if you
are trying it on purpose and a particular implementation does not
order variables in memory in the order you expect, or puts gaps in to
maintain data alignment, etc., you have no right to be surprised.
