当其他类对象作为本类成员，构造时先构造类对象，再构造自身

#include<iostream>
#include<cstring>
using namespace std;
class Phone
{
public:
	Phone(string pName)
	{
		m_PName = pName;
		cout << "调用phone构造函数" << endl;
	}
	string m_PName;
};
class Person
{
public:
	Person(string name, string pName) :m_Name(name), m_Phone(pName) { cout << "调用person构造函数" << endl; }
	string m_Name;
	Phone m_Phone;
};
void test01()
{
	Person p("zhagnsan", "iphone 13 promax");
	cout << p.m_Name << "use:" << p.m_Phone.m_PName << endl; //person调用成员m_Phone,m_Perosn再调用成员m_PName
}
int main()
{
	test01();
}
