【问题描述】:
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补充之前,该项目正在运行,但我认为我修补了一条特定的线路,一切似乎都被打破了。
我收到的错误消息是: '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,如果这里发布时间太长。
感谢您的宝贵时间。

【问题讨论】:
-
这是怎么编译的?您有
Board.h,包括Player.h,其中包括Board.h,其中包括Player.,h等。您还在Player类中使用Board引用,在Board中使用Player班级。换句话说,你有循环引用。 -
您发布的函数声明有 3 个参数,因此这不能解释错误消息。正如其他人已经指出的那样,由于您#included 相当广泛,我希望您无意中引用了您发布的源文件之外的其他源文件,可能是您的版本 1 源文件?
-
是的,我现在看到了我的方式的错误。我想我有点超出了我目前正在阅读的教科书并且让自己感到困惑。感谢您的帮助!
