Question

我正在编写拼写检查程序，将用户的文本文件与字典进行比较，以查看他们输入的单词是否在字典中。如果没有，则打印错误消息以告知用户特定单词是错误的。我已尝试过以下代码的多种变体，但未获得所需的结果。嵌套while循环中的某些内容会将其丢弃。这段代码处于草案阶段，我必须使其更具内存效率等并整理起来。我只是想让它先工作。谢谢！

编辑：根据以下提示稍微修改了代码。它现在读取第一个单词，并说它在字典中。然后显示第二个单词，但字典扫描循环不运行，程序挂起。我知道它嵌套的while循环导致了我无法理解的问题！

解决此问题的通常方法是首先阅读字典并构建哈希表。然后，您将从输入文件中一次读取一个单词，如果散列表上不存在该单词，则标记错误。
