类和对象—类对象作为类成员—C++

1.定义

当类中的成员为其他对象时，我么们称之为 对象成员。

2.注意

先调用对象成员的构造，再调用本类的构造；析构相反。

3.代码结果

4.代码表现

#include<iostream>
using namespace std;
#include<string>
class phone
{
public:
	phone(string name)
	{
		m_phonename = name;
		cout << "phone构造函数调用" << endl;
	}
	~phone()
	{
		cout << "phone析构函数调用" << endl;
	}
	string m_phonename;
};
class person
{
public:
	person(string name,string pname):m_name(name),m_phone(pname)
	{
		cout << "person构造函数调用" << endl;
	}
	~person()
	{
		cout << "person析构函数调用" << endl;
	}
	void playgame()
	{
		cout << m_name << "使用" << m_phone.m_phonename << "牌手机" << endl;
	}
	string m_name;
	phone m_phone;
};
void fun()
{
	person p("张三", "苹果16pro max");
	p.playgame();
}
int main()
{
	fun();
	system("pause");
	return 0;
}
