用桥接模式实现在路上开车这个问题，其中，车可以是car或bus，路可以是水泥路或沥青路。

 

 

 

#include<iostream>
#include<string>
using namespace std;
class Chexing {
public:
    virtual void run()=0;
};
class Bus:public Chexing{
public:
    void run(){
        cout<<"公共汽车,";
    }
};
class Car:public Chexing {
public:
    void run(){
        cout<<"汽车,";
    }
};
class Road:public Chexing{
public:
    virtual void run()=0;
};
class LiqingRoad:public Road{
private:
    Chexing *chexing;
public:
    LiqingRoad(Chexing *chexing1)
    {
        chexing=chexing1;
    }
    void run() {
        chexing->run();
        cout<<"在沥青路行驶"<<endl;
    }
};
class ShuiniRoad:public Road{
private:
    Chexing *chexing;
public:
    ShuiniRoad(Chexing *chexing1){
        chexing=chexing1;
    }
    void run() {
        chexing->run();
        cout<<"在水泥路行驶"<<endl;
    }

};
int main()
{
        Road *road1=new ShuiniRoad(new Car);
        Road *road2=new LiqingRoad(new Car);
        Road *road3=new ShuiniRoad(new Bus);
        Road *road4=new LiqingRoad(new Bus);
        road1->run();
        road2->run();
        road3->run();
        road4->run();
}
