本文介绍了如何在C++中实现特殊成员函数（构造、析构、拷贝构造、拷贝赋值和虚函数），以及类的继承，包括英雄类、法师类和射手类的定义，以及在主函数中通过实例化这些类并调用虚函数来模拟战斗过程。

完成特殊成员函数

#include <iostream>

using namespace std;

class Person
{
    string name;
    int *age;
public:
    //构造，析构，拷贝构造，拷贝赋值
    Person():age(new int ){}
    Person(int *age,string name):name(name),age(new int (*(age))){}
    ~Person()
    {delete age;}
    Person(const Person& other):name(other.name),age(new int (*(other.age))){}
    Person& operator=(const Person& other)
    {
        *(this->age)=*(other.age);
        this->name = other.name;
        return *this;
    }
    
};

class Stu:public Person
{
    const double score;
public:
    //构造，析构，拷贝构造，拷贝赋值
    Stu():score(12){}
    Stu(double score):score(score){}
    Stu(double score,string name,int *age):Person(age,name),score(score){}
    ~Stu(){}
    Stu(const Stu& other):Person(other),score(other.score){}
    Stu& operator=(const Stu& other)
    {
        Person::operator=(other);
        return *this;
    }
     
};

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 name，int hp,int attck，写一个无参构造、有参构造，类中有虚函数:void Atk(){monster-=0;}；法师类，公有继承自英雄类，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 attck;
public:
    Hero(){}
    Hero(string name,int hp,int attck):name(name),hp(hp),attck(attck){}
    virtual void Atk()
    {monster-=0;}
};
class Master:public Hero
{
    int ap_ack;
public:
    Master(int ap_ack,string name,int hp,int attck):Hero(name,hp,attck),ap_ack(ap_ack){}
    void Atk()
    {
        monster-=ap_ack+attck;
    }
};
class Shooter:public Hero
{
    int ad_ack;
public:
    Shooter(int ad_ack,string name,int hp,int attck):Hero(name,hp,attck),ad_ack(ad_ack){}
    void Atk()
    {
        monster-=ad_ack+attck;
    }
};
int main()
{
    Shooter s1(500,"Draven",1500,500);
    Master m1(800,"ali",1000,100);
    int i=0;
    while(monster>=0)
    {
        s1.Atk();
        if(monster<=0)
        {
            cout << "monster还剩" << monster <<endl;
            break;
        }
        m1.Atk();
        cout << "monster还剩" << monster <<endl;
        i++;
    }
    cout << "time is taken "<< i << " s " <<  endl;
    return 0;
}
