Beep at different tones

I want the computer to beep at 2/3 different tones for my pong game (when hitting the padde, when hitting the wall, when it falls down)

how do i do this ? what's the simplest way ?

in Turbo C++, if your making it for DOS, include stdlib.h, conio.h, and stdio.h, and use the function sound().

Code:

---

sound(100); //low
sound(500); //medium
sound(1000); //ear-pearceing scream

---

what about bc++ 5.5 ?
i need to compile this game only with that..

also, how do i contrl the length of the tone?

oh yeah im sorry

Code:

---

sound(100);
delay(500);//half a second
nosound();

---

How do i do this in borland c++ 5.5 ?
