我正在创建一个函数来加载一个哈希表，如果我的代码看起来像这样，我就会遇到分段错误

bool load(const char *dictionary)
{
    // initialize vars
    char *line = NULL;
    size_t len = 0;
    unsigned int hashed;

    //open file and check it
    FILE *fp = fopen(dictionary, "r");
    if (fp == NULL)
    {
        return false;
    }

    while (fscanf(fp, "%s", line) != EOF)
    {
        //create node
        node *data = malloc(sizeof(node));
        //clear memory if things go south
        if (data == NULL)
        {
            fclose(fp);
            unload();
            return false;
        }

        //put data in node
        //data->word = *line;
        strcpy(data->word, line);

        hashed = hash(line);
        hashed = hashed % N;

        data->next = table[hashed];
        table[hashed] = data;
        dictionary_size++;
    }

    fclose(fp);
    return true;
}

但是如果我更换

char *line = NULL;by char line[LENGTH + 1];（其中长度为 45）

有用。它们不是“等效”的吗？

while (fscanf(fp, "%*s", LENGTH, line) != EOF)
