图书信息管理程序（3人）
具体要求实现如下功能：
1）定义与图书相关信息的数据结构，包含书号，书名，作者，出版社，出版时间，总页数，定价等信息。
2）添加数据功能：向已有图书信息表中添加新的图书信息的功能。
3）删除数据功能：在已有数据中删除某个图书的相关数据，保证其他数据的正常使用。4）查询数据功能：在已有数据中查找某些图书的相关数据，并给出相关的查找结果；查找可以根据图书的书名或者出版社进行，如果查找成功，给出具体信息，否则给出没有找到的提示。
5）修改数据功能：对已有的图书信息进行修改。
6）排序功能：根据要求按照书号或者出版时间进行排序。
7）添加功能选择菜单。

帮我看看 怎搞 知道写链表的写个 链表的程序 给我吧。。谢谢 不会的 帮我看下这个程序要怎么改 谢谢

好贴，我今天又长见识了……谢了！

高手啊

麻烦结贴子啊

为了帮你做一个，差点把我绕进去了，我这个是双向链表的，输入的时候就是按学号排序的，所以要按要求排序还得自己好好想想，界面之类的自己去弄吧：

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
