1.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。

代码实现：

#include 

using namespace std;

//全局变量
int monster = 10000;

//英雄类
class Hero
{
protected:
    string name;
    int hp;
    int attack;

public:
    Hero(){}  //无参
    Hero(string name,int hp,int attack):name(name),hp(hp),attack(attack){}  //有参
    //虚函数
    virtual void Atk(){monster -= 0;}

};

//法师类
class Ap:public Hero
{
    int ap_atk = 50;
public:
    Ap(){}
    Ap(string name,int hp,int attack,int ap_atk):Hero(name,hp,attack),ap_atk(ap_atk){}

    void Atk()  //函数重写
    {
        monster-=(attack+ap_atk);
    }
};

//射手类
class Adc:public Hero
{
    int ac_atk = 100;
public:
    Adc(){}
    Adc(string name,int hp,int attack):Hero(name,hp,attack){}

    void Atk()  //函数重写
    {
        monster-=(attack+ac_atk);
    }
};

int main()
{
    Ap a1("小法师",1000,100,90);
    Adc b1("小炮",1200,120);

    int i=0;
    while(monster > 0)
    {
        a1.Atk();
        i++;
        if(monster > 0)
        b1.Atk();
        i++;
    }

    cout<< i << endl;


    return 0;
}
