Towers Of Hanoi Visual

[Quiksilver89]

hey,
I'm working on a program the simulates the Towers Of Hanoi puzzle. The user enters the number of disks, and the program uses winbgim's BGI interface to do a simple simulation of the puzzle being solved. I already have the algorithm to solve the problem, but I'm having trouble with the graphics.
I don't know how I would go about showing the disks actually being "moved" on the screen. Heres my program so far. It constructs the pegs, and shows the first disks. All i have to do is show them being moved, according to the algorithm.

Thanks!

if (n == 1){
cout << "Move from " << s << " to " << d << endl;

}else{
Hanoi(n-1, s, i, d);
Hanoi(1, s, d, i);
Hanoi(n-1, i, d, s);
}
}

int n;
