有以下类，完成特殊成员函数

#include <iostream>

using namespace std;
class Person
{
    string name;
    int *age;
public:
    //有参构造
    Person(string name,int age):name(name),age(new int(age)){}
    //析构函数
    ~Person()
    {
        delete age;
    }
    //拷贝构造
    Person(const Person &other):name(other.name),age(new int(*(other.age))){}
    //拷贝赋值
    Person &operator=(const Person &other)
    {
        if(this!=&other)
        {
            this->name=other.name;
            *(this->age)=*(other.age);
        }
        return *this;
    }
};
class Stu:public Person
{
    const double score;
public:
    //无参构造
    Stu():Person("路人甲",18),score(60.0){}
    //有参构造
    Stu(string name,int age,double score):Person(name,age),score(score){}
    //析构函数
    ~Stu(){}
    //拷贝构造
    Stu(const Stu &other):Person(other),score(other.score){}
    //拷贝赋值
    Stu &operator=(const Stu &other)
    {
        if(this!=&other)
        {
            Person::operator=(other);
        }
        return *this;
    }

};


int main()
{
    cout << "Hello World!" << endl;
    return 0;
}

2尝试写:定义一个全局变量int monster=10000;定义一个英雄类Hero，受保护的属性，string nameint hp,int attck，写一个无参构造、有参构造，类中有虛函数:void Atk()(monster-=0;};法师类，公有继承白英雄类，私有属性:int ap ack;写有参,重写父类中的虚函数，射手类，公有继承自英雄类，私有属性:int ad ack;写有参构造，重写父类中的虚函数，主函数内完成调用，判断怪物何时被杀死。

#include <iostream>
using namespace std;
int monster=10000;
class Hero
{
protected:
    string name;
    int hp;
    int attack;
    //无参构造
    Hero():name("路人甲"),hp(100),attack(5){}
    //有参构造
    Hero(string name,int hp,int attack):name(name),hp(hp),attack(attack){}
    virtual void Atk(){monster-=0;}
};
class Mage:public Hero
{
    int ap_ack;
public:
    Mage(string name,int hp,int attack,int ap_ack):Hero(name,hp,attack),ap_ack(ap_ack){}
    void Atk()
    {
        int t=0;
        while(monster>=0)
        {
            monster-=ap_ack;
            t++;
        }
        cout << "经历了" << t << "秒的战斗，怪物被" << name << "消灭了" << endl;
        monster=10000;
    }
};
class Archer:public Hero
{
    int ad_ack;
public:
    Archer(string name,int hp,int attack,int ad_ack):Hero(name,hp,attack),ad_ack(ad_ack){}
    void Atk()
    {
        int t=0;
        while(monster>=0)
        {
            monster-=ad_ack;
            t++;
        }
        cout << "经历了" << t << "秒的战斗，怪物被" << name << "消灭了" << endl;
        monster=10000;
    }
};

int main()
{
    Mage m1("维肯",500,23,95);
    m1.Atk();
    Archer a1("安娜",250,33,125);
    a1.Atk();
    return 0;
}
