You are right, *(a + i) is precisely equivalent to a[i].
Any compiler that gets that wrong is badly broken.

Moreover, many programs say

	a + i

instead of

	&a[i]

so there is a fair premium on getting at least that part of it right.

You might ask your instructor for an example of a compiler that
doesn't get *(a + i) right.
