With the minor problem that `a[3]` isn't valid.

Depends how you use it (&a[3], sizeof(a[3])). But its type is still char.

IIRC, both of those are undefined.

&a[3] is allowed, it's a one-past-the-end-of-the-array pointer. &a[4] would be UB (if it were evaluated).

sizeof(a[3]) is not evaluating a[3], so it also isn't UB.
