试题五（共15分）

阅读下列说明和C++代码，将应填入（n）处的字句写在答题纸的对应栏内。

【说明】

某咖啡店当卖咖啡时，可以根据顾客的要求在其中加入各种配料，咖啡店会根据所加入的配料来计算费用。咖啡店所供应的咖啡及配料的种类和价格如下表所示。

【C++代码】

include <iostream>

include <string>

using namespace std;

const int ESPRESSO_PRICE = 25;

const int DRAKROAST_PRICE = 20;

const int MOCHA_PRICE = 10;

const int WHIP_PRICE = 8;

class Beverage { //饮料

（1） ：string description;

public:

（2） (){ return description; }

（3） ;

};

class CondimentDecorator : public Beverage { //配料

protected:

（4） ;

};

class Espresso : public Beverage { /／蒸馏咖啡

public:

Espresso () {description="Espresso"; }

int cost（）{return ESPRESSO_PRICE; }

};

class DarkRoast : public Beverage { //深度烘焙咖啡

public:

DarkRoast(){ description = "DardRoast"; }

int cost(){ return DRAKROAST_PRICE; }

};

class Mocha : public CondimentDecorator { ／／摩卡

public:

Mocha（Beverage*beverage）{ this->beverage=beverage; }

string getDescription(){ return beverage->getDescription()+",Mocha"; }

int cost(){ return MOCHA_PRICE+beverage->cost(); }

};

class Whip :public CondimentDecorator { //奶泡

public:

Whip（Beverage*beverage） { this->beverage=beverage; }

string getDescription() {return beverage->getDescription()+",Whip"; }

int cost() { return WHIP_PRICE+beverage->cost(); }

};

int main() {

Beverage* beverage = new DarkRoast();

beverage=new Mocha( （5） ）;

beverage=new Whip（ （6） ）;

cout<<beverage->getDescription()<<"￥"<<beverage->cost() endl;

return 0;

}

编译运行上述程序，其输出结果为：

DarkRoast, Mocha, Whip ￥38
