The problem is that cout, printf and similar functions buffer their
output until a newline is reached or until an input action is
requested.  Mixing cout and getch (which reads directly from the
console without worrying about the output buffers other systems like
printf and cout use) is a bad idea because it will result in what you
describe.  Use getchar (or something like that).
