Nice, but just a little thing:
switch(toUpper(returned)) {
case 'Y': break checkLoop;
case 'H': {low=guess; break;}
case 'L': {high=guess; break;}
default: break;
}
PS: Yeah you can you tolower() too!

This piece is something I wrote quickly for /r/dailyprogrammer
(By the way, is the person who has been posting D solutions to
that on here?)
It's a really simple piece, but it shows %s, breaking from a
loop from inside a switch, etc.
