move(int from, int to, int n){

  move(from,other,n-1);
  printf("move %d from %d to %d\n",n,from,to);
  move(other,to,n-1);
}
main(){
  move(1,2,5);
}

ozo's code has the gist of it.

To explain, the idea is that you have 3 poles with a given number of disks, each disk being progresivley larger than the next (stacked like a pyramud).

You have to move all the diskd from the first pole to the third pole while keeping the following rules:

1. You can only move one disk ata time.

2.- You can never place a larger disk on top of a smaller disk.

3.- You can move any disk to any pole in any order.

Still with the Hanoi tower, what is a C++ program for the algorithm below;
tower(positive integer n, peg i, peg j , peg k)
// move the top n disks on peg i to peg k using peg j
if n=1 then
  move top disk on peg i to peg k
else
  tower(n-1,i,k,j)
  move top diskk on peg i to peg k
  tower(n-1,j,i,k)
