11.25c++继承、多态

练习：

编写一个 武器类
class Weapon{int atk;
}编写3个武器派生类：短剑，斧头，长剑
class knife{int spd;
}class axe{int hp;
}class sword{int def;
}编写一个英雄类
class Hero{int atk;int def;int spd;int hp;
public:所有的get set 方法void equipWeapon(Weapon*)根据传入的武器不同，英雄获得不同的属性加成
}

代码实现： 

#include <iostream>
#include <cstring>
#include <cstdlib>
#include <myhead.h>
using namespace std;  class Weapon;
class Hero{
private:int atk;int def;int spd;int hp;
public:Hero(int atk=0,int def=0,int spd=0,int hp=0):spd(spd),hp(hp),def(def),atk(atk){}void setAtk(int atk){this->atk=atk;	}void setSpd(int spd){this->spd=spd;}void setHp(int hp){this->hp=hp;}void setDef(int def){this->def=def;}int getAtk(){return this->atk;}int getSpd(){return this->spd;}int getHp(){return this->hp;}int getDef(){return this->def;}void equipweapon(Weapon* w);void showProptery(){cout << "h p=" << hp << endl;cout << "spd=" << spd << endl;cout << "def=" << def << endl;cout << "atk=" << atk << endl;cout << "-------------" << endl;}
};class Weapon{
private:int atk;
public:Weapon(int atk=0):atk(atk){}void setAtk(int atk){this->atk=atk;}int getAtk(){return this->atk;}virtual void addProptery(Hero& hero){}
};

class Axe:public Weapon{

};

};
void Hero::equipweapon(Weapon* w){w->addProptery(*this);
