For that, I recomment abandoning your old school book, and getting
excellent, modern and concise "Accelerated C++":

getchar() is close, but not exactly equivalent.
Reading keyboard *immediately* (without waiting for carriage return)
is rather tricky on UNIX.

That's also quite tricky, because there is no 'screen' that you
can clear. If you really want it, you can read about curses terminal
