用装饰模式模拟手机功能的升级过程：简单的手机(SimplePhone)在接收来电时，会发出声音提醒主人；而JarPhone除了声音还能振动；更高级的手机(ComplexPhone)除了声音、振动外，还有灯光闪烁提示。

实验要求：

1.提交类图；

2.提交源代码；

3.注意编程规范。

 

1、类图

 

 

2、源代码

#include <iostream>

#include <string>

#include <list>

using namespace std;

 

class Phone

{

public:

    Phone() {}

    virtual ~Phone() {}

    virtual void ShowDecorate() {}

};

 

// 具体的手机类

class SimplePhone : public Phone

{

    string namePhone;

 

public:

    SimplePhone(string name) : namePhone(name) {}

    ~SimplePhone() {}

    void ShowDecorate()

    {

        cout << endl << namePhone << ":" << endl;

    }

};

 

// 装饰类

class DecoratorPhone : public Phone

{

private:

    Phone* m_phone;  // 要装饰的手机

 

public:

    DecoratorPhone(Phone* phone) : m_phone(phone) {}

    virtual void ShowDecorate() { m_phone->ShowDecorate(); }

};

 

// 具体的装饰类

class DecoratorPhoneA : public DecoratorPhone

    void ShowDecorate() { DecoratorPhone::ShowDecorate(); AddDecorate(); }

    void AddDecorate() { cout << "发出声音提示主人电话来了" << endl; } // 增加的装饰

};

 

// 具体的装饰类

class DecoratorPhoneB : public DecoratorPhone
