recursive function

[brianptodd]

I am writing a recursive function that seems to work, but I have to also include a while loop to ask the user for the depth of the recursion. This is resulting in an endless loop.

Here is the code:

 void recurse(int count, int depth);	//	function prototype

 int main()
 {

	 int depth;
	 cout << "Please enter a number for recursion depth, or -1 to exit: " << endl;
	 cin >> depth;
	 while (depth != depth *2)
	 {
		 for (int counter = depth -(depth * 2); counter <= depth; counter++)
	 	 {
				recurse(counter, depth);
		 }

	cout << "Please enter a number for recursion depth, or -1 to exit: " << endl;
}
	return 0;

	 }


void recurse(int count, int depth)
{
	if (count < 0)
		cout << "This was written by call number " << (count * -1) << "." << endl;
	else if (count > 0)
		cout << "This was ALSO written by call number " << count << "." << endl;
	else if (count == depth)
		return;
}

Any ideas on how to break from this while loop?
