Hi all,
Going quite methodically through K& R ( as some of you can attest
to!), I have never seen a big diffference in declaring a function
within "main" or "ahead" of it. Now, (p119, K&R II), the discussion
states that "functions "whatever" " should be declared ahead of
main.
Is there a good reason for this?

In Standard C, functions cannot be declared "within" main(); these are
called nested functions ...

No, they're called function declarations are are certainly allowed
within main() and any other function. You're confusing declaration
with definition. You can't define a function within another function
in Standard C.
