Are we allowed to assume that row-major order arrays are totally
contiguous in memory for any platform (by your example of address
a[0][4])? For arrays of structures or objects (or some other big unit),
is it not possible for their locations in memory to be non-contiguous?
Also i'm assuming that you cannot access a[0][4] directly because wouldn't
that cause an out-of-bound subscript error? So you would instead do some
manual pointer arithmetic to get that address, right?
Thanx for any response.
