#include <iostream>

using namespace std;

//合成复用法则

//尽量使用合成/聚合，尽量不要使用类继承

class car_fa{

public:

    virtual re_some() = 0;

};

//宝马

class baoma:public car_fa{

public:

    virtual re_some()

        cout<<"宝马"<<endl;

};

//奔驰

class benchi:public car_fa{

public:

    virtual re_some()

        cout<<"奔驰"<<endl;

};

//car_fa是car类的成员属性

class car{

public:

    car(car_fa* ca){

        this->ca = ca;

    go_work(){

        ca->re_some();

public:

    car_fa* ca;

};

//利用成员属性进行输出

void test01()

    car_fa* ca = NULL;

    ca = new baoma;

    car* c_some = NULL;

    c_some = new car(ca);

    c_some->go_work();

int main()

    test01();

    cout << "Hello World!" << endl;

    return 0;
