代碼如下:

#include <iostream> #include <list> using namespace std;class AbstractHero { public:virtual void update() = 0; };class HeroA :public AbstractHero { public:HeroA(){cout << "英雄A正在打BOSS" << endl;}virtual void update(){cout << "英雄A停止打BOSS，處于待機(jī)狀態(tài)" << endl;} };class HeroB :public AbstractHero { public:HeroB(){cout << "英雄B正在打BOSS" << endl;}virtual void update(){cout << "英雄B停止打BOSS，處于待機(jī)狀態(tài)" << endl;} };class HeroC :public AbstractHero { public:HeroC(){cout << "英雄C正在打BOSS" << endl;}virtual void update(){cout << "英雄C停止打BOSS，處于待機(jī)狀態(tài)" << endl;} };class HeroD :public AbstractHero { public:HeroD(){cout << "英雄D正在打BOSS" << endl;}virtual void update(){cout << "英雄D停止打BOSS，處于待機(jī)狀態(tài)" << endl;} };class HeroE :public AbstractHero { public:HeroE(){cout << "英雄E正在打BOSS" << endl;}virtual void update(){cout << "英雄E停止打BOSS，處于待機(jī)狀態(tài)" << endl;} };class AbstractBoss { public:virtual void addHero(AbstractHero *hero) = 0;virtual void deleteHero(AbstractHero *hero) = 0;virtual void notify() = 0; };class BossA :public AbstractBoss { public:virtual void addHero(AbstractHero *hero){heroList.push_back(hero);}virtual void deleteHero(AbstractHero *hero){heroList.remove(hero);}virtual void notify(){for (list<AbstractHero *>::iterator it = heroList.begin(); it != heroList.end(); it++){(*it)->update();}}public:list<AbstractHero *> heroList; };void test01() {AbstractHero *heroA = new HeroA;AbstractHero *heroB = new HeroB;AbstractHero *heroC = new HeroC;AbstractHero *heroD = new HeroD;AbstractHero *heroE = new HeroE;AbstractBoss *bossA = new BossA;bossA->addHero(heroA);bossA->addHero(heroB);bossA->addHero(heroC);bossA->addHero(heroD);bossA->addHero(heroE);cout << "heroC 陣亡" << endl;bossA->deleteHero(heroC);cout << "bossA死了，通知其他英雄停止攻擊" << endl;bossA->notify(); }int main() {test01();return 0; }
