C语言图书管理系统

Question

设计要求

1、任意选定以下一个题目完成

2、模块化程序设计

3、锯齿型程序书写格式

4、必须上机调试通过

设计报告格式：

1、设计题目

2、模块功能说明（如函数功能、入口及出口参数说明，函数调用关系描述等）

3、源程序清单和执行结果：清单中应有足够的注释

图书信息管理系统设计

图书信息包括：图书号、书名、作者名、出版单位、出版时间、价格等。

试设计一图书信息管理系统，使之能提供以下功能：

1、图书信息录入功能(图书信息用文件保存)－－输入；

2、图书信息浏览功能－－从文件中读取图书信息并输出；

3、图书信息查询功能－－从文件中按作者查询指定的图书信息；

4、从文件中读取图书信息，按价格排序输出；

5、从文件中删除指定图书号的图书信息；
谢谢各位大侠了，是我的考试题目，跪谢了啊
