Thread: Need help w/ debugging errors

I'm trying to write a program to give the factorial of a number from the user. If you've read the www.cprogramming.com tutorial on recursion then you'll know why. The problem is that the compiler I'm using (Dev-C++) is giving errors for code I think is right... (in other words its wrong :P)

Heres the code:

Code:

#include <iostream.h>

//Generate factorial numbers

int yournum;
int final;
int working;
    
int main()
    {
    cin>>yournum;
    final=yournum;
    working=yournum-1;
    if(yournum<=0)
        {
        cout<<"Error sorry";
        }
        else
        {
        factorial();
        }
    cout<<"\nPress any key to exit";
    cin.get();
    return 0;
    }

void factorial()
    {
    if(working<=0)
        {
        cout<<"Your number was !", yournum, " which equals ", final;
        return;
        }
    working=working-1;
    working*final=final;
    factorial();
    }

(sorry if its too big but its not as if its a huge program...)

There errors are line 21 which is "factorial();" and line 36 which is also "factorial();".
What am I doing wrong?? :S

Thanks....

Code:

#include <iostream>  // Note, its not iostream.h
include namespace std; // When changing iostream.h to iostream include this, otherwise you will get errors.

// Function prototype:
void factorial();

//Generate factorial numbers

int yournum;
int final;
int working;
    
int main()
{
    cin>>yournum;
    final=yournum;
    working=yournum-1;
    if(yournum<=0)
        {
        cout<<"Error sorry";
        }
    else
        {
        factorial();
        }
    cout<<"\nPress any key to exit";
    cin.get();
    return 0;
}

void factorial()
{
    if(working<=0)
        {
        cout<<"Your number was !", yournum, " which equals ", final;
        return;
        }
    working=working-1;
    working*final=final;
    factorial();
}

Thanks
