That's zero marks on any exam I ever wrote. You didn't properly read the
business requirements that specified the need for a function ;) Also,
the version you showed isn't shared in any way, it has local scope, so
unless it's defined in global scope and you're working in global scope
(since I don't see a global declaration) then it's not very
accessible :))
Cheers,
Rob.
