[实验任务一]：双向适配器

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>

#include <string>

 

using namespace std;

 

class Cat

{

public:

    virtual void catlook(){}

    virtual void catchM(){}

};

 

class CatImpl:public Cat

{

public:

    void catlook()

    {

        cout<<"猫的样子"<<endl;

    }

    void catchM()

    {

        cout<<"猫抓老鼠"<<endl;

    }

};

 

class Dog

{

public:

    virtual void doglook(){}

    virtual void wang(){}

};

 

class DogImpl:public Dog

{

public:

    void doglook()

    {

        cout<<"狗的样子"<<endl;

    }

    void wang()

    {

        cout<<"狗汪汪叫"<<endl;

    }

};

 

 

class Adapter : public Cat,Dog

{

private:

    Dog *DogImpl;

    Cat *CatImpl;

public:

    Adapter(Dog *DogImp,Cat *CatImp)

    {

        DogImpl=DogImp;

        CatImpl=CatImp;

    }

    virtual void doglook()

    {

        cout<<"狗模仿";

        CatImpl->catlook();

    }

    virtual void wang()

    {

        cout<<"狗模仿";

        CatImpl->catchM();

    }

    virtual void catlook()

    {

        cout<<"猫模仿";

        DogImpl->doglook();

    }

    virtual void catchM()

    {

        cout<<"猫模仿";

        DogImpl->wang();

    }

};

 

 

int main()

{

    DogImpl *DogImp=new DogImpl();

    CatImpl *CatImp=new CatImpl();

    Adapter *adapter = new Adapter(DogImp,CatImp);

    adapter->catlook();

    adapter->catchM();

    cout<<"**************"<<endl;

    adapter->doglook();

    adapter->wang();

 

    return 0;

}

3.注意编程规范。
