一. 思维导图

二.练习

全局变量，int monster = 10000;定义英雄类hero，受保护的属性string name，int hp,int attck；公有的无参构造，有参构造，虚成员函数 void Atk(){blood-=0;}，法师类继承自英雄类，私有属性 int ap_atk=50；重写虚成员函数void Atk(){blood-=(attck+ap_atk);}；射手类继承自英雄类，私有属性 int ac_atk = 100；重写虚成员函数void Atk(){blood-=(attck+ac_atk);}实例化类对象，判断怪物何时被杀死。

#include <iostream>using namespace std;int monster = 10000;class Hero {
protected:string name = "";int hp = 0;int attack = 0;
public:Hero(){}Hero(string name, int hp, int attack):name(name), hp(hp), attack(attack){}virtual void atk(){}
};class Mega: public Hero {
private:int ap_atk = 50;
public:Mega(){}Mega(string name, int hp, int attack):Hero(name, hp, attack){}void atk() {monster -= (attack+ap_atk);}
};class Adc: public Hero {
private:int ac_atk = 100;
public:Adc(){}Adc(string name, int hp, int attack):Hero(name, hp, attack){}void atk() {monster -= (attack+ac_atk);}
};int main()
{Mega mega("法师", 100, 0);Adc adc("射手", 100, 0);int attackCount = 0;while(monster > 0) {mega.atk();adc.atk();attackCount++;}cout << "攻击" << attackCount << "次后，杀死怪物" << endl;return 0;
}

结果展示:
