	std::string m_Name;
	int m_Score;
	int x, y, z;
public:
	Entity()
		:m_Name("[Unknown]"),m_Score(0),x(0),y(0),z(0)//initialize in the order of how var are declared
	{
	}
	Entity (const std::string& name) 
		:m_Name(name)
	{}
	const std::string& GetName() const { return m_Name; };
};
int main()
{
	Entity e1;
	std::cout << e1.GetName() << std::endl;
	Entity e2("Caleb");
	std::cout << e2.GetName() << std::endl;
	std::cin.get();
