我正在使用C语言搜索程序。程序应该将包含单词搜索的文件（data1，data2，data3）作为输入，并仅使用已解决的单词（包含在solution1，solution2中）输出搜索，解决方案3）。该程序编译良好，但当我尝试运行它时，没有任何反应。我的代码如下。任何帮助表示赞赏。

答案 0 :(得分：0)
我认为可能会破坏您的代码的一些问题：
在get_Array方法中，在第二个for循环中，它现在的方式是它需要这样的输入：
A space B space C space \n
请注意最后一个空格？我不确定那是你的意图。只需删除最后一个getchar();即可。
同样重要的是要注意fgets()还会包含NewLine吃掉字符串的结尾，所以如果要分隔像'word\word\n'这样的单词，这可能是一个问题。
