调试时,结果查看问题;shared_ptr;智能指针
struct T_Test_D
	{
	public:
		T_Test_D(void){Init();}
		~T_Test_D(void){}
	public:
		int na;
		CString strName;
		double db;
		char charc;

	public:
		void Init(void)
		{
			na = 1;
			db = 2.555;
			charc = 'c';
			strName = _T("Test");
		}
	};
	std::shared_ptr<T_Test_D>  ppp(new T_Test_D);
	int na = ppp->na;
调试时,为何运行语句std::shared_ptr<T_Test_D>  ppp(new T_Test_D)后,智能指针ppp成员具体值无法查看,显示为问号?
运用语句int na = ppp->na,则可以查看到na = 1;
