c++ - C++ 中的 Tic-Tac-Toe 帮助，如何制作循环以便 Tic Tac Toe 游戏每次都会重复棋盘

Question

我是初学者，所以我的代码很乱。我还没有完整地评论这个游戏，所以如果你需要澄清一些变量，我可以给你。

(顺便说一句，这是一个要求制作井字游戏的c++项目)

我的主要问题是，我将如何重复我的棋盘(每次有人在井字游戏中移动时都会更新)？我想不出这样做的方法，所以如果有人给我想法，而不是直接的答案，我将不胜感激。

下面我的代码只是为了让您了解我在做什么，以及如果您对如何修复我的代码有任何建议(即组织或错误，发生的可能性为 100%)。

Answer 1

您可以使用用户输入循环整个程序。 while (getline(std::cin, input)。并用适当的符号更新二维数组。我建议你使用常量来表示 X 和 O。这样代码就会清晰. 而且我还建议你将重复的代码移到函数中，这同样会增加清晰度。
