番外-软件设计（5）

实现一个双向适配器，使得猫可以学狗叫，狗可以学猫抓老鼠。

实验要求：

1. 画出对应的类图；

2.提交源代码；

#include<iostream>

using namespace std;

class Cat{

public:

    virtual void miao()=0;

    virtual void catchs()=0;

};

class Dog{

public:

    virtual void wang()=0;

    virtual void run()=0;

};

class RealCat:public Cat{

public:

    void miao(){

        cout<<"喵喵叫！"<<endl;

    }

    void catchs(){

        cout<<"抓老鼠！"<<endl;

    }

};

class RealDog:public Dog{

public:

    void wang(){

        cout<<"汪汪叫！"<<endl;

    }

    void run(){

        cout<<"跑跑跑！"<<endl;

    }

};

class Adapter:public Cat,public Dog{

private:

    static Cat *cat;

    static Dog *dog;

public:

    void setCat(Cat *c){

        cat=c;

    }

    void setDog(Dog *d){

        dog=d;

    }

    void wang(){

    }

    void catchs(){

    }

    void run(){

        cout<<"小狗学小猫！"<<endl;

        cat->catchs();

    }

    void miao(){

        cout<<"小猫学小狗："<<endl;

        dog->wang();

    }

};

Cat* Adapter::cat=new RealCat();

Dog* Adapter::dog=new RealDog();

int main(){

    Adapter adapter;

    adapter.run();

    adapter.miao();

    return 0;

}

3.注意编程规范。
