Static members.....creating problem

Following is the code I had written for a class list. It contains a static int Pos, which I wanted to initialise.

Code:

---

class list 
{
        struct node *head, *tail;
    static int Pos ;
public:
    list();
        ~list();
        void enqueue (const int&);
        int deque () ;
        int pop() ;
        struct node* find(const int) const;
       
};

int list::Pos = 0;

---

However, upon compiling the program I get the following linker error
Main.obj : error LNK2005: "private: static int list::Pos" (?Pos@list@@0HA) already defined in list.obj
Debug/Static1.exe : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.


Where am I redifining the static int Pos ?

Is this is the wrong way to initialise a static data member ?

Please help.

put this line

int list::Pos = 0;

in list.cpp instead of list.h

you will find that it magically is fixed. The reason is when you have a variable declared in a .h and include it in multiple .cpp files you get both cpp's trying to create the same variable name.
