我认为在尝试读取.txt文件时可能会出现某种内存泄漏。它只是停止响应和崩溃我对编程一般都是新手。

这是完整的不完整代码：

WordsReadIn似乎没有增加，可能导致除以0。

这个循环：

    while (fgets(input, 100, pToFile)) {
        sscanf(input, "%s", WordList[WordsReadIn]);

    }

我写的是：

    while (fgets(input, 100, pToFile)) {
        sscanf(input, "%59s", WordList[WordsReadIn]);
        ++WordsReadIn;
    }

当试图在日食上运行程序时它会崩溃
