That's often a matter of taste.  Once you grasped the C pointer
semantics, I usually find

        foo + i

much easier to parse than

        &foo[i].

Both expressions are always equivalent.

Of course,

        *(foo + i)

is terrible, because

        foo[i]

is much clearer then.

Anyway, for the compiler, it should never make any difference, because
these expressions are identical in their effect.  If the compiler can
(statically) bounds-check &foo[i], I don't see why it would not be
able doing so for foo + i.  (Most of the time, it cannot check it
though.)
