Thread: Bloody recursive thing

Hi!
How are ya!
Anyway, I've just begun learning programning and I was trying the whole recursive program tutorial. I dunno what the problem is but every time the recursive function returns an integer to main it changes into 30866468. Here is what I got:

Code:

#include <iostream>

using namespace std;

int recursion (int x, int y);
int main ()
{
    int num_user;
    int num_result = 0;
    cout<<"Input a number\n";
    cin>> num_user;
    num_result = recursion(num_user, 1);
    cout<< num_result;
    _flushall();
    cin.get();
}

int recursion (int x, int y)
{
    y *= x;
    if (x == 1)
    {
          return y;
    }
    recursion ((x - 1), y);
}

Thanks for any help.
