c - Ncurses:比较输入和文本文件中选定的单词

Question

我想做“下落的单词”打字游戏(在单词落在控制台底部之前输入单词)，但我陷入困境，因为我不知道我的声明是否有效。

现在这个功能:

• 打开包含单词列表的文本文件

• 从文件中选择随机单词(我没有这样做，是在网上找到的)。

• 打印下落动画(列数也是随机的)

问题是:我不知道如何将变量“输入”与当前下降的单词进行比较。到目前为止，我对 scanw 函数的尝试都失败了，我不确定 fgets 是否会更好。

编辑:我尝试使用 strcmp 和 if 函数，但它并没有真正帮助 - 我的意愿是让这个词落下，同时我可以写这个词。如果两个字符串相同，它应该打印“SAME”，但它不起作用，我不知道为什么......

这在 while 循环之前打开了文件。输入斜线“/”结束循环。
