技術標籤：C++面向物件

#include<iostream>
#include<string>
using namespace std;
class Phone {
public:
	Phone(string pname) {
		m_pname = pname;
		cout << "Phone的建構函式呼叫" << endl;
	}
	string m_pname;
};

class Person {
public:
	Person(string name, string pname):m_name(name)
 
,m_phone(pname) {
		cout << "person的建構函式呼叫" << endl;
	}
	string m_name;
	Phone m_phone;
};
void test01() {
	Person p("張三","蘋果");
	cout <<p.m_name<< "拿著 "<<p.m_phone.m_pname<< endl;
}
int main() {
	test01();
	return 0;
}

可以從執行結果中看出當一個類中有其他類的物件作為本類成員，先構造其他類物件，然後再構造本身。
