class Watch
{
public:
 Watch(Time t) :m_tTime(t.m_iHour,t.m_iMinute,t.m_iSecond)
 {

 }
 void display()
 {
  cout << m_tTime.m_iHour << endl;
  cout << m_tTime.m_iMinute << endl;
  cout << m_tTime.m_iSecond << endl;
 }
public:
 Time m_tTime;
};

类Watch是这样实现的，但是运行后错误列表里针对mian中Watch w(t);有个：IntelliSense: no instance of constructor "Watch::Watch" matches the argument list argument types are: (Time)。不知道怎么修改，神奇的是不影响运行出结果。
