#include <iostream>
using namespace std;
static int blood = 10000;
class hero
{
protected:
    string name;
    int hp;
    int attack;
public:
    hero(){}//无参构造
    hero(string name,int hp,int attack):name(name),hp(hp),attack(attack){}//有参构造
   virtual void  Atk()
    {
        blood -= 0;
    }
};
class Mage:public hero
{
private:
    int ap_atk = 50;
public:
    Mage(){}
    Mage(string name,int hp,int attack):hero(name,hp,attack){}
    void Atk()
    {
        blood -= (attack += ap_atk);
    }
};

class Archer:public hero
{
private:
    int ap_atk = 100;
public:
    Archer(){}
    Archer(string name,int hp,int attack):hero(name,hp,attack){}
    void Atk()
    {
        blood -= (attack += ap_atk);
    }
};

int main()
{
   Mage m("Mage",1000,500);
   Archer a("Archer",200,200);
    int sum = 0;
    while(blood > 0)
    {
        m.Atk();
         //a.Atk();
        sum++;
        cout << blood << endl;
    }
     cout << "小怪在法师的第" << sum   << "攻击下被杀死了"<<endl;

    return 0;
}

运行效果如下
