实验9：桥接模式

本次实验属于模仿型实验，通过本次实验学生将掌握以下内容：

1、理解桥接模式的动机，掌握该模式的结构；

2、能够利用桥接模式解决实际问题。

[实验任务一]：两个维度的桥接模式

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。

实验要求：

1.画出对应的类图；

2.提交源代码；

3.注意编程规范。

1、类图

 

源代码

#include <iostream>

using namespace std;

class Transportation

{

public:

    virtual void drive(){}

};

class Car:public Transportation

{

public:

    void drive()

    {

        cout<<"小轿车";

    }

};

class Bus:public Transportation

{

public:

    void drive()

    {

        cout<<"大巴";

    }

};

class Road

{

public:

    Transportation* transportation;

 

    Road(Transportation* transportation)

    {

        this->transportation=transportation;

    }

    virtual void driveOnRoad(){}

};

class CementRoad:public Road

{

public:

    CementRoad(Transportation* transportation):Road(transportation)

    {

    }

    void driveOnRoad()

    {

        transportation->drive();

        cout<<"行驶在水泥路"<<endl;

    }

};

class BituminousRoad:public Road

{

    public:

    BituminousRoad(Transportation* transportation):Road(transportation)

    {

    }

    void driveOnRoad()

    {

        transportation->drive();

        cout<<"行驶在柏油路"<<endl;

    }

};

int main()

{

    Transportation* transportation;

    Car car=Car();

    transportation=&car;

    CementRoad(transportation).driveOnRoad();

}
