编写一个如下场景：
有一个英雄Hero类，私有成员，攻击，防御，速度，生命值，以及所有的set get 方法
编写一个 武器 Weapon 类，拥有私有成员攻击力，以及set get 方法
编写一个 长剑 Sword 类，继承自武器类，拓展属性 生命值，以及set get 方法
编写一个 匕首Blade类，继承自武器类，拓展属性 速度，以及set get 方法
编写一个 斧头 Axe类，继承自武器类，拓展属性 防御力，以及set get 方法

武器Weapon类里面，要求有一个多态函数，叫做 equip 函数
英雄Hero类里面，要求有一个公开函数，equipWeapon(Weapon* w)
实现功能：英雄既可以装备长剑，也可以装备短剑，也可以装备斧头，但是要求装备不同的武器，英雄需要获得不同的属性加成

}

输出结果：
