对象类型的数据域声明调用

#include <iostream>using namespace std;class Time{public:Time(){hour = 2;minute = 30;second = 40;}void p(){cout << hour << ":"<<minute<<":"<<second<< endl;system("pause");}Time(int hour, int minute, int second){}private:int hour;int minute;int second;};class Action{public:void k(){time.p();}private:    Time time;};int main(){Action action;action.k();return 0;}

本来在测试构造函数初始化列表，变成写一段很没用的类套类的代码。总之就是看一下对象类型的数据域怎么声明，怎么调用。
