Help with static member object

[zanklob]

Hello,
I am trying to set a class object as a member of another class but I am missing something. When I declare my object as global it works fine. Here is an example of my code:

#include <iostream>

class Print
{
public:
	Print(){}
	~Print(){}
	void PrintInt( int a_Data )
	{
	std::cout << a_Data << std::endl;
	}
};
//Print a;
class Data
{
public:
	Data(){}
	Data(int a_Data)
	{
		m_Data = a_Data;
	}
	~Data(){}
	void Print()
	{
		a.PrintInt(m_Data);
	}
private:
	int m_Data;
	static Print a;
};

int main()
{
	Data b(5);
	b.Print();
	return 0;
}

You have a function named Print at line 23.
When you declare a at line 29 you're referencing Print.
Are you referring to the class or the function?
I changed lines 23 and 35 to PrintIt and it compiled without a problem.

You shall define the static member before main. For example

Print Data::a;

@vlad from moscow: I would prefer to have the Print object as a member of class Data.

@AbstractionAnon: When you say that you changed line 23 do you mean like this?

	void PrintInt()
	{
		a.PrintInt(m_Data);
	}

because it seems strange and I get errors.

It is a static member so it should be defined as I showed. Inside the class it is a declaration not the definition of the object.

Should I still declare it in the class as static Print a;?
