C语言程序设计报告(菜单+源码+测试).docx

一：系统功能基本功能：图书的录入，删除，查找，和导入导出等。图书属性：书号，书名，第一作者，版次，出版年等。菜单功能:1. Input Records（输入若干条记录）从键盘一次输入一本书的信息，存放到结构体数组中，然后显示。提示信息，确认是否输入下一条记录。2. Display All Records（显示所有记录）按顺序显示所有记录，每屏显示10条记录，按键继续显示下一屏。3. Delete a Record（按书名查找，删除一本书）输入待删除书的书名，显示该书名的所有书目，提示输入待删除书目的书号，提示是否删除，确认后，删除该书。4. Sort（排序）以书名为升序排列数组5. Insert a record（插入一条记录）以书名为序排列的数组中插入一条记录，插入后，数组仍然有序。输出插入成功后的信息。6. Query（查找并显示一个记录）输入书名，查找并显示包含该书名的所有图书信息7. Add Records from a Text File（从文件读入图书信息到结构体数组中）用户可事先建立一个文本文件Dictory.txt。存放所有图书信息，文件格式如下：21182高等数学刘浩荣 5 同济大学出版社 20137300 物理化学王德明 2 化学工业出版社 20158. Write to a Text File将数组中的全部记录写入文件Records.txt中，要求格式与Dictory.txt相同。0. Quit（退出图书管理系统）新增加菜单功能：9. Change a record修改某一条记录的值a. Menu显示菜单b. Clear Screen清屏c.
