二、系统菜单的部分功能及相应函数1 查阅图书findbook()1.1按书名查询 namefindbook()1.2按作者查询 authorfindbook()2 借阅图书lendbook()3 管理系统3.1增加图书addbook()3.2删除图书delbook()—考虑输入错误的情况3.3修改图书资料changebook()3.4书籍统计bookcount()3.5职工管理系统3.5.1增加员工addemploy()3.5.2删除员工delemploy()3.5.3修改员工资料changemploy()3.5.4员工统计employcount()3.6学生管理系统3.6.1申请新卡addcar()3.6.2删除卡号delcar()3.6.3借书统计lendcount()3.6.4卡号统计carcount()4 还书returnbook()0 退出三、主要数据文件 book.txt 存放书名 car.txt 卡号文件 record.txt 存放每个读者借阅的书 employ.txt 职工信息 student.txt 四、要求 1、只能使用c语言，源程序要有适当的注释，使程序容易阅读。 以前对信息管理主要是利用文本纸质介质的方式进行手工处理， 对图书借阅情况（借书时长、 超过可借阅的图书数量、 所借图书已过期、 库存的某本图书的库存量还有多少、 某本图书的流向等）的统计都是通过人工检索， 对读者的借阅权限以及借阅天数和可借数量等都采用人工计算，手抄进行记录， 数据的信息处理量非常大， 比如一个人去借书， 首先的查询资料改用户的借阅卡是否有效， 知道有效后又得查询借阅的图书数量是否超出规定的数量， 得知没有超出可借数量， 才可以出借图书， 这时又得把这次的借阅信息记录下来， 在读者信息添加借书信息， 在库存减少一本该书的数量。4.网上图书馆，可在网上查阅各类图书的目录及借阅情况-“图书查阅”，同时可在网上“预约借书”。

需 求 分 析 1. 依据题目要求以及现实中图书馆的需求，应将该系统分为两大模块：图书管理和会员管理。图书管理模块中包括对图书的增加、修改、删除、查询、统计等操作，以及对图书借入借出服务。会员管理包括对会员卡号的申请、删除、统计等操作。2. 界面应该具有友善、直观、易操作等特点，本系统采用数字输入选择操作。数据处理流程图系 统 源 码 #include <stdio.h> #include <stdlib.h> #include <string.h> struct student { int cardnum;
