谁能告诉我我的错误？

Question

这应该将我的输入保存到另一个txt文件.程序将询问您的txt文件的名称.

FILE *save;
char filename[100];

scanf ("%s", filename);

save = fopen ("filename", "w");

current = head;

while (current != NULL)
{
    fprintf (save, " %s %s %d", current -> name, current -> tel, current -> age);
    current = current -> next;
}

fclose(save);

Answer 1

那就是在这里:

    scanf ("%s", filename);

    save = fopen ("filename", "w");

你能看到你在那里做了什么吗？(提示filename)
