一、程序及输出

#include<iostream>
using namespace std;
#include <string>

class Phone
{
public:
	Phone(string pName)
	{
		cout << "phone 的有参构造调用" << endl;
		m_PhoneName = pName;
	}

	~Phone()
	{
		cout << "phone 的析构函数调用" << endl;
	}

	string m_PhoneName;
};

class Game
{
public:
	Game(string gName)
	{
		cout << "Game 的有参构造调用" << endl;
		m_GameName = gName;
	}
	~Game()
	{
		cout << "Game 的析构函数调用" << endl;
	}

	string m_GameName;
};

class Person
{
public:

	Person(string name, string pName, string gName) : m_Name(name), m_Phone(pName), m_Game(gName)
	{
		cout << "Person 的有参构造调用" << endl;
	}

	void PlayGame()
	{
		cout << m_Name << "拿着 << " << m_Phone.m_PhoneName << " >> 牌手机，玩着 :" << m_Game.m_GameName << endl;
	}

	~Person()
	{
		cout << "Person 的析构函数调用" << endl;
	}

	string m_Name; //姓名
	Game  m_Game;  //游戏
	Phone m_Phone; //手机
};

void test01()
{
	//当其他类对象 作为本类成员，先构造其他类对象，再构造自身，析构的顺序和构造相反
	Person p("张三", "苹果", "王者荣耀");
	p.PlayGame();

	Person p2("李四", "三星", "消消乐");
	p2.PlayGame();
}


int main(){
	test01();
	system("pause");
	return EXIT_SUCCESS;
}

输出：

二、分析与总结

当其他类对象 作为本类成员，先构造其他类对象，再构造自身，析构的顺序和构造相反
