c++ - 制作了一个 Tic-Tac-Toe 控制台应用程序，但我有多个无法解决的错误

Question

祝大家圣诞快乐。我制作了一个小井字游戏来练习使用 OOP 技术，这是我这样做的第二个应用程序。在我对评分系统进行一些细微的添加之前，该项目正在运行，但我认为我修改了一条特定的线，但似乎一切都坏了。

我收到的错误信息是:'语法错误:标识符'board'''Player::PlayerMove::' 函数不接受 3 个参数'

这是我所有的代码。抱歉，如果在这里发帖时间太长。

感谢您的宝贵时间。

您在 Player.h 中包含了 Board.h，在 Bord.h 中包含了 Player.h。循环包含是不可能的。此外，在 Player.h 中包含一个头文件本身是没有意义的，例如 Player.h。要解除循环包含，请使用前向声明。

板.h:

#pragma once
// #include <Payer.h>   <- remove this
// #include <Boarder.h> <- remove this
#include <vector>

class Player; // forward declaration of class Player (you can use Player* and Player& in header file)

播放器.h:

#pragma once
// #include <Payer.h>   <- remove this
// #include <Boarder.h> <- remove this
#include <vector>

class Boarder; // forward declaration of class Boarder(you can use Boarder* and Boarder& in header file)
