Question

我是C ++的早期程序员，我想用C ++在CMD上创建一个简单的小游戏。我为什么得到

严重错误C1075：在左括号之前发现文件结尾，并且读写文件不起作用

我检查了每一行，都没发现错误。

我检查了每一行，没有发现任何错误。我没有在任何角色上看到“弯曲”的红线。也许我的眼睛错了。

如果您看到完整的错误消息，则会得到类似

的信息。

严重错误C1075：在左括号之前发现文件结尾，并且读写文件不起作用

这意味着您没有关闭足够多的块来打开它们（{比}多）。

要解决此问题，您应该更好地缩进代码源。

诸如indent之类的某些工具将为您完成此任务。您甚至可以找到一些工具online。

但是您的代码中还有其他问题：

没有main
缺少内容
if (answerOfUser = answerExpected)（不是第四个问题上的=，而不是==）

也就是说，将代码拆分为不同的功能以提高可读性要容易得多。

由于您的游戏要问一系列问题，因此您可以从一个函数开始逐个问题...但是，这一点在https://codereview.stackexchange.com/

上有更多的位置。

为什么我会收到致命错误C1075，我检查了代码，没有发现任何错误
