c++ - 我的 Tic Tac Toe 游戏代码中的一个问题

Question

我用 C++ 制作了一个井字游戏。我不知道如何输出合适的板，所以我制作了一个带有标记为 1-9 的数组的网格，让用户输入数字以告诉计算机将他的镜头放在哪里。第二个玩家是电脑。我很高兴，因为这是我的第一个工作程序，但代码有问题，有时，并非总是，在退出前输出“无效”，我用这个词告诉用户输入无效数字.有人能帮我理解为什么会这样以及我代码中的逻辑吗，因为过了一段时间，连我自己都对自己写的东西感到困惑。非常感谢，谢谢。

Answer 1

你的错误是由于这一行:

if (entered >= 1 || entered <= 9)

您需要使用&& 而不是||。
