Can't access a static private data member from a friend function?

[JustSomeGuy]

I have a class with a private data member and I want to access it
from a friend function, but Visual Studio 2003 .NET won't let me.

class MyClass
{
private:
static int level;
public:
friend ostream & operator<<(ostream & x, const MyClass & c);
}

int MyClass::level = 0;

ostream & operator<<(ostream & x, const MyClass & c)
{
O << c.level;
}

Post some code that has some hope of compiling. Among other things, you've
omitted the semicolon at the end of the definition of MyClass, you've used an
undeclared variable O in the implementation of operator<<, and the function
doesn't return a value.

#include <iostream>

using namespace std;

class MyClass
{
private:
static int level;
public:
friend ostream & operator<<(ostream & x, const MyClass & c);
}
missing ;
int MyClass::level = 0;

ostream & operator<<(ostream & x, const MyClass & c)
{
O << c.level;
x << c.level; //or "x << MyClass::level;"
return x; // undefined behaviour if you forget to return x
}

Sumit.

I doubt that... Thank you.
