c - 如何使用 .h 中的枚举在玩家之间切换？

Question

有谁知道为什么当我运行这段代码时，它会进入 P2_TURN 以及如何使这个枚举处于事件状态，当 P2 移动时，P1 就会进入，无论谁赢得正确的语句，都将从 print_status() 给出…还有一个更简单的/分配获胜者的更干净的方式。在 void process_move(struct game* p_game_info) 处，有一种方法可以用用户输入替换数字 0-8 而无需 switch case…。很抱歉这个查询有点困惑，但现在已经是凌晨 4 点了，所以希望你能原谅我……

你的问题确实很困惑。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。您需要一个双等号。
