Using this code, I'm able to make it count from the number the user inputs down to zero. I need to find a way to count up from zero back up to the number, using recursion factorial again.
I've tried adding another function that's similar, but got no luck:

``````int Factorial2(int iNum)
{
cout<<"We are at number: "<<iNum<<endl;
if (1 >= iNum)
{
cout<<"We are at number: ";
return 0;
}
else
{
return Factorial(iNum + 1);
}
}``````

I've tried a lot of things.(Better than the above code too.)
Anyone have an idea how I can do this?

Well down is easy, you stop at a constant.

But counting up, the place where you stop is a variable.
Consider passing the current value AND the target value as parameters.

Thanks! Worked like a charm! :)
