 Because the *length of a string* is by definition "the number of bytes

Yes, as you can easily see if you read 7.1.1p1 for yourself.
I can't tell if you're trying to understand C strings, or you're
suprised by how they're defined, or you object to how they're defined,
or you don't accept how they're defined, or something else.  I'm getting
the impression that you're arguing for the sake of arguing, but perhaps
that's unfair of me.  If you have a wider point, perhaps you could let
us know what it is.
I'll also note that you asked why strlen() doesn't include the null, I
answered, and you snipped most of my answer.  Of course there's usually
no need to quote all of an article you're replying to, but it would be
helpful if you'd mark your deletions.  (I usually use "[...]".)  You've
given the impression that I gave you just a one-sentence answer to your
question, which is not the case.
