static member question

[jasonkong1989]

Question:

The below code compiles, but i am not sure how. I have a static member
variable that, when defined, calls a private constructor. I was under
the impression that the private constructor would be inaccessable to
the static member variable. Where am I mistaken?

class MyClass
{

public:
static MyClass m_myclass;
static int myfunc(){return 5;}

private:
MyClass(int x=9){int y = x; y++;} //private default constructor

};

MyClass MyClass::m_myclass(9); //m_myclass is defined, private
constructor is called

int main( )
{
int x = MyClass::m_myclass.myfunc(); //MyClass::m_myclass is
actually used
x++;
return 0;

}

Static members are members, so they have access to private parts of the
class.

int x = MyClass::m_myclass.myfunc();

I would normally use MyClass::myfunc() just since the function is static.
