Let's not be so pedantic that we miss the fact that an unspecified return
type defaults to int (this is ANSI), even though it's considered bad style
(where this is not the appropriate place to nitpick about that, because it
varies from person to person).  The only thing he was missing was a return
statement returning a value at the end of the function.

getche is in conio.h, not stdio.h.  It is in fact non-ANSI.
