C++图书管理系统 C++编写实现图书管理系统
噙笑wink_ 人气:0想了解C++编写实现图书管理系统的相关内容吗,噙笑wink_在本文为您仔细讲解C++图书管理系统的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:C++图书管理系统,C++图书系统,C++图书管理,下面大家一起来学习吧。
C++编写的一个图书管理系统,供大家参考,具体内容如下
2018大一的课设,搬到这纪念一下,共1200多行代码
为图书管理人员编写一个图书管理系统,图书管理系统的设计主要是实现对图书的管理和相关操作,包括3个表:
图书信息表——存储图书的基本信息,包括书号、书名、作者、出版社、出版日期、存馆数量、定价等。
读者信息表——存储读者的基本信息,包括学号、姓名、学院、专业班级等。
图书借阅表——存储读者借书的相关信息,包括学号、姓名、书号、书名、借阅日期、应还日期、归还日期等。
用菜单选择方式完成了以下功能:
1、图书信息添加功能:包括书号、书名、作者、出版社、出版日期、存馆数量、定价等。
2、图书信息查询:分别按书名, 按作者名,
按出版单位等进行查询。
3、图书信息排序:按书号、书名等按升序进行排序。
4、图书信息的修改、删除:按书号或书名进行图书的修改和删除。
5、读者信息添加功能:包括学号、姓名、学院、专业、班级等。
6、读者信息查询:分别按学号、姓名、班级等进行查询。
7、读者信息排序:按学号、学院等按升序进行排序。
8、读者信息的修改、删除:按学号+姓名进行读者信息的修改和删除
9、图书借阅:输入学号+书号,如果该书图书信息表中的存馆数量大于0,则可以借出,借出相应数量后修改图书信息表中的存馆数量,在图书借阅表添加该同学的借阅。
10、图书归还:输入学号+书号,修改图书信息表中的存馆数量,在图书借阅表中记录该同学的归还时间。
11、图书借阅查询:分别按学号、书名、学院等进行查询。
