这篇文章主要讲解了“C++实现简易图书馆管理系统的代码怎么写”,文中的讲解内容简单清晰,易于学习与理解,下面请大家跟着小编的思路慢慢深入,一起来研究和学习“C++实现简易图书馆管理系统的代码怎么写”吧!
思路
在本程序中共有四个类:
book类:此类有书的基本信息:书名,编号,作者,价格等,和基本的get()和set()方法。类图如下:
library类:此类中有一个存放的书的数组,并且可以对书进行,查询,借阅,归还,添加,等相关操作。类图如下:
reader_infor类:此类中有读者的相关信息:名字,学号,年级,借书数量。和基本的get()和set()方法,类图如下:
reader_admin类:此类中有一个存放读者对象的数组,并且可以进行添加读者,修改读者信息等操作。类图如下:
登陆页面如下
读者页面
管理员页面
在本程序过程中的不足:
书和读者的存储是通过静态数组实现的,如果用动态数组的话更好一点。
2.还有一些其他点感觉写的不是很好,但还不知道要怎么改。
后面有时间会再完善一下。
