数据类:
基础类:读者最大借书量、最长借书时间(按天计算)。这两个都是类成员;
日前类:包括年月日，重载输入运算符时，要进行数据的合法性检验;重载输出运算符时，按照“年/月/日”形式输出，重载+运算符;
借阅记录类:包括日期、书号、读者学号、类型（借出/还回/续借)、图书类型(基础/文学休闲/专业);
读者类:学号、姓名、专业、班级、已借图书数量、借阅记录向量;
图书类∶书号、书名、作者、出版社、出版日期、图书类型（基础/文学休闲/专业)、馆藏总量、在馆数量、借阅记录向量;

操作类:
数据成员:图书/学生/借阅记录向量;
成员函数:对图书进行文件读写、在图书向量内完成对图书基本信息的增删查改;
对学生进行文件读写、在学生向量内完成对学生基本信息的增删查改;借阅记录的管理和统计功能后续添加;
作业要求:
程序能够正常运行，数据文件要经过多次运行测试，每次运行，内容要有相应的变化。数据用真实的，不要出现张三、李四这样的名字，数据不要在记事本中添加，一起通过程序搞定。
