Question

以下是我的程序的一部分，它从用户输入中获取N个单词，然后将它们存储在一个数组中。

然而，当我运行程序时，我收到了这个错误：

runtime error - illegal array, pointer or other operation
Execution stopped here in main() in wordchains.c at line 168:

assert(array[i] != NULL);

 -->        scanf(FORMAT_STRING, array[i]);
    //printf("scanf: %d current word:%s\n", length, array[i]);


Values when execution stopped:

i = 0
array[i] = "cast"

在这个阶段我找不到任何错误......

scanf：运行时错误 - 非法数组，指针或其他操作
