How to debug putchar()

[skiabox]

I am trying to debug putchar with xcode but I can't see the characters in the console window?
Any ideas on this one?

My psychic debugger suggests that you flush stdout before expecting any output in the console window:

putchar(c);
fflush(stdout);

Unless the character being printed is guaranteed to be '\n', of course. That character forces a flush.
