This is not a bug. This is because printf() (stdout) is buffered in DJGPP,
which means that it doesn't print the data until you flush it
(fflush(stdout);) or when a newline is found.

So either you put an fflush(stdout) in front of getch(), or you put the
newlines last in each string, or you use cprintf() instead.

This issue is covered in the FAQ too, look it up there!
