图书管理系统如何建立.
建立一图书管理系统,该系统包括下面几部分:
1.图书资料库:每本图书信息为:书编号,书名,作者,出版社,数量(总数,库存数).
2.图书录入部分.新购图书加入到图书资料库链表末端.
3.图书删除部分,按书名删除该书全部信息.
4.图书查找部分,按书名查找并显示该书信息.
想了几天了,没有思路,请各位高手来帮忙解决.谢了.
使用二进制文件方式存储数据，系统以菜单方式工作
图书管理信息中包括:
1、新进图书基本信息的输入。
2、图书基本信息的查询。
3、对撤消图书信息的删除。
4、为借书人办理注册。
5、办理借书手续。
6、办理还书手续。
机会难得，不要放弃。过程和结果同样重要。呵呵
