图书馆信息管理C＋＋源程序

Question

急！！ 急！！ 跪求！ 希望各位高手帮帮忙！ 感激涕零！
图书馆图书信息管理程序设计。图书信息包括主编、出版社、出版年、版次、ISBN书号、书名、定价、拥有本数、借出本数、现余本数。要求程序实现下列5个功能：（1）借出功能（被借之书“借出本数”增1，“现余本数”减1）；（2）归还功能；（3）查找功能（需指定书的“ISBN书号”或其他信息，查找该书目前借出、余存信息）；（4）将图书数据存入文件；（5）将图书数据从文件读出
还要能够 进行图书信息的录入，删除等管理操作
分数 还可追加

读者信息可以不要 重点是图书信息
2楼的 是抄的 我也找到过啊
辛苦哪为大哥自己写下 按要求 谢谢
