#include <iostream>

using std::cout;
using std::endl;

class Test {
public:
	static int sCounter;

	Test();
	static int GetCounter();

private:
	int myLevel;
};

int Test::sCounter = 0;

Test::Test() :myLevel()
{
	sCounter++;
	cout << "object " << sCounter << " created" << endl;
}

int Test::GetCounter()
{
	return sCounter;
}

int main()

	cout << "sCounter : " << Test::sCounter << endl;;

	Test o1, o2, o3, o4;
