裝飾模式:
通過AbstractEquipment裝飾AbstractHero，使其heroA增加了一個穿裝備的功能。

代碼如下:

#include <iostream> using namespace std;class AbstractHero {public:virtual void showStatus() = 0;int hp;int mp;int at;int df; };class HeroA :public AbstractHero { public:HeroA() {hp = 0;mp = 0;at = 0;df = 0;}virtual void showStatus(){cout << "血量 = " << hp << endl;cout << "魔法 = " << mp << endl;cout << "攻擊 = " << at << endl;cout << "防御 = " << df << endl;} };class AbstractEquipment :public AbstractHero { public:AbstractEquipment(AbstractHero *hero){this->hero = hero;}virtual void showStatus(){}AbstractHero *hero; };class Kuangtu :public AbstractEquipment { public:Kuangtu(AbstractHero *hero):AbstractEquipment(hero){}void addKuangtu(){cout << "英雄穿上狂徒之后" << endl;this->hp = this->hero->hp;this->mp = this->hero->mp;this->at = this->hero->at;this->df = this->hero->df+30;delete this->hero;}virtual void showStatus(){addKuangtu();cout << "血量 = " << hp << endl;cout << "魔法 = " << mp << endl;cout << "攻擊 = " << at << endl;cout << "防御 = " << df << endl;} };class WujinzhiKinfe :public AbstractEquipment { public:WujinzhiKinfe(AbstractHero *hero):AbstractEquipment(hero){}void addWujinzhiKinfe(){cout << "英雄拿上無盡之刃之后" << endl;this->hp = this->hero->hp;this->mp = this->hero->mp;this->at = this->hero->at+30;this->df = this->hero->df ;delete this->hero;}virtual void showStatus() {addWujinzhiKinfe();cout << "血量 = " << hp << endl;cout << "魔法 = " << mp << endl;cout << "攻擊 = " << at << endl;cout << "防御 = " << df << endl;} };void test01() {AbstractHero *hero = new HeroA;hero->showStatus();cout << "---------------------" << endl;hero = new Kuangtu(hero);hero->showStatus();hero = new WujinzhiKinfe(hero);hero->showStatus(); }int main() {test01();return 0; }
