With, OR WITHOUT, an MMU, it is legal C code!
int A[10];

A[10] = 0;

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.

As does assembler. ;-)
