c - 如何在.h 中使用枚举的玩家之间切换？
问题描述
有谁知道为什么当我运行此代码时它会用于 P2_TURN 以及如何使这个枚举处于活动状态，当 P2 移动时，P1 会去，并且无论谁赢得了正确的语句，都会从 print_status() 中给出……还有更简单/更清洁的方法来分配获胜者。在 void process_move(struct game* p_game_info) 是否有一种方法可以用用户输入替换数字 0-8 而无需切换大小写……抱歉，这个查询有点混乱，但现在已经是凌晨 4 点了，所以希望你能原谅我…。

解决方案
你的问题确实很混乱。我不确定您真正想知道什么，但请注意“else if (p_game_info->status=P2_TURN){”是错误的。你需要一个双等号。
