『叁』 c语言图书管理系统
我简单给你说一下吧。
1、首先定义数据结构
图书结构：图书编号、图书名称、单价、作者、存在状态
人员结构：人员编号（学生为学号，教师为工作编号）、姓名、性别等
借书结构：人员编号、图书编号、借书时间、还书时间
2、由于是C系统，通常情况下，数据要存储在文件中，因此，还需要定义文件结构：图书、人员、借书信息。
为了数据处理速度，可将借书信息中已经还书的信息单独放在还书信息中，借书信息中的数据只是已经借出还没有归还的数据。
3、系统功能定义，以及编码。
由于系统太过庞大，你还是自己试着做一下吧，应该可以做好的。
学习本身就是做程序，如果有困难，可以上我们团队提问题，随时恭候！
祝学习进步！
