Could someone enlighten me?

Code:

---

#include <iostream>
using namespace std;
void count ( int x )
{
    cout << x << endl;
    if ( x > 0 ) count ( x - 1 );
}
int main()
{
    count ( 10 );
}

---

There is no problem with the code, I just have a question about it. How come that one counts down from 10 to 0, but if you put the "cout" after the "if," it counts up from 0 to 10? Is it because the condition is stated before the variable? Any help would be appreciated.

10s a bit hard lets look at 3

heres your func swopped...

Code:

---

{   
    if ( x > 0 ) count ( x - 1 );
    cout << x << endl;
}

---

now call with x=3

x is greater than 0 so count(2)
in count(2)
x is greater than 0 so count(1)
in count(1)
x is greater than 0 so count(0)
in count(0)
x is 0 so cout x
back in count(1)
cout x
back in count(2)
cout x
back int count(3)
cout x

so u see 0,1,2,3 is printed.

Now work that thru for the original and you will see why its forwards one way and back the other.

Oh, wow. Thanks for the help, that solves that question.
