C++中当其他类对象作为本类成员，构造是先构造类对象，再构造自身，析构的顺序与构造相反

当其他类对象作为本类成员，构造是先构造类对象，再构造自身，析构的顺序与构造相反

#include 
#include 
using namespace std;

class Phone
{
public:
	Phone(string Name)
	{
		cout << "Phone的构造函数调用" << endl;
		m_PhoneName = Name;
	}
	~Phone()
	{
		cout << "Phone的析构函数调用" << endl;
	}
	string m_PhoneName;
};
class Person
{
public:
 //Phone m_Phone=p.Name  隐式转换法
  //当其他类对象作为本类成员，构造是先构造类对象，再构造自身，析构的顺序与构造相反
	Person(string name, string phoneName) :p_Name(name), p_Phone(phoneName)
	{
		cout << "Person的构造函数调用" << endl;
	}
	~Person(){
		cout << "Person的析构函数调用" << endl;
	}
	string p_Name;
	Phone p_Phone;
};

void test01(){
	Person p("张三", "vivo xs");
	cout << p.p_Name << "拿着" << p.p_Phone.m_PhoneName << endl;
}
int main() 
{
	test01();
	system("pause");
	return 0;
}

输出：

Phone的构造函数调用
Person的构造函数调用
张三拿着vivo xs
Person的析构函数调用
Phone的析构函数调用
