C++类中的成员可以是另一个类的对象,称该成员为对象成员。
构造的顺序:先调用对象成员的构造,再调用本类的构造;
析构顺序:先调用本类的析构,再调用对象成员的析构。
#include<iostream> #include<string> using namespace std; class Ball { public: Ball(string bname) { b_name = bname; cout << "Ball构造函数调用!" << endl; } ~Ball() { cout << "Ball析构函数调用!" << endl; } public: string b_name; }; class WLM { public: WLM(string name,string bname):m_name(name),m_ball(bname) { cout << "WLM构造函数调用!" << endl; } ~WLM() { cout << "WLM析构函数调用!" << endl; } public: string m_name; Ball m_ball; }; void test() { WLM wlm("万利萌","篮球"); cout << wlm.m_name << "打" << wlm.m_ball.b_name << endl; } int _tmain(int argc, _TCHAR* argv[]) { test(); system("pause"); return 0; }
