Just a quick point: that's not a good name because it confuses two
possible meanings of 'size': size in bytes and a less technical meaning
of size in terms of the number of elements.

I know you just have to pick a name out of thin air when there is no
surrounding program, but in this particular case, where the question is
all about the 'sizeof' various objects, it seems worth pointing out.

And, since I'm already replying...  That may be your preference, but I
think you should also ask if it is shared by the student.  Some students
want to move on without fully understanding everything (usually because
they get bored otherwise) and they hope (and often find) that things
fall into place.  Others don't, of course, but I don't think there's a
hard and fast rule that's good for everyone.  (All this assumes the
luxury of one-to-one tuition.  In a class, you can never suit everyone
in terms of pace.)
