how to simulate loops for/while using a recursion

how to build for and while loops using a recursion?

Code:

---

void countdown(int n) {
    if (n == 0) return;
    printf("%d\n", n);
    countdown(n - 1);
}

Why would you want to do this, though? It's much simpler with loops, and you won't need to worry about stack overflow.

thanks :)

Code:

---

void LoopFor ( int y, int n){
        int x;

        for (x=y; x<=n; x++)
          LoopFor (x, y, n);
}

void main (void)
{
    LoopFor (0, 100);

}

That won't compile, and recurses 99! times, I should think [which will probably blow the stack to smithereens].
