任务描述 本关任务：编写一个能实现游戏角色变身的小程序。 相关知识 为了完成本关任务，你需要掌握：1.如何定义抽象类（接口），2.如何使用抽象类。 题目内容 已知游戏中常见人物状态State抽象类，包括站立（Idle），行走（Run），攻击(Attack)，死亡(Dead)等动作。在游戏中有角色hero类，拥有人物状态同时还拥有血量，攻击力，防御力等属性,有怪物类Monster,怪物有血量，攻击力，防御力，怪物类型等属性。 已知角色可以变身为怪物，现在main函数中，模拟某个角色在正常情况下以及在变身状态下的各种状态操作(输入1为正常hero，输入2则变身为monster)。要求，使用抽象类及的基类指针实现。 编程要求 根据提示，在右侧编辑器补充代码，完成程序。 测试说明 平台会对你编写的代码进行测试： 测试输入： 1 预期输出： hero is idleling... hero is attack... hero is running... hero is dead... 测试输入： 2 预期输出： Monster is idleling... Monster is attack... Monster is running... Monster is dead... 开始你的任务吧，祝你成功！
