写好了 恩~~幸好我以前写过的程序还在论坛上保存好~~~稍微改改就可以用了
不过不知道符合要求不，我不知道图书馆管理程序有什么功能啊！！ 也不知道界面要求采用什么样的界面。 所以现在用的是最简单的----命令提示符~~~ ^o^
流星雨，你来看看应该修改那里，好要增加和修改那些功能。 改好了我一起把注释写上去。
使用说明：
本程序采用的是双链表的结构，并且头链HEAD和尾链END是指定的，不能更改。 <HEAD>-----<记录1>----<记录2>---- ... ----<记录3>----<END>
很多操作都是围绕now_point（当前节点）来进行的。
new 在当前节点后插入一个新的记录，并且把当前节点指向新记录； del 删除当前节点的记录，当前节点自动指向前一个记录； ver 显示版本号，没什么用，纯粹娱乐； list 显示所有记录； point 显示当前节点所指向的记录； uppoint 当前节点往前移一条记录，不改变当前节点的指向； downpoint当前节点往后移动一条记录，同样不改变当前节点的指向； find 可以按照name或者tel来进行查找，如果找到，当前节点自动指向它； cls 清屏； help帮助命令 quit 退出程序。
