Some discussion should probably be made of buffering issues that can
occur while mixing reading and writing on the command-line. I.e., the
program might start waiting for the user input before it actually prints
out the line telling the user what to enter. It's been a long time since
I have had to deal with this (normally user input is provided through
the program arguments). However, I think it involves flushing
stdin/stdout buffers with fflush().
