Hi!大家好，这里是霍田的博客！
最近学校里组织了一场跨学科，我也发现了表现契机：图书管理系统(Book Managerment System)。
于是就"小小的"编写了一下，目前共191行，包含开始页面+美化+版本号+增加书籍+查找书籍+借阅图书+还回图书，（注意：帮助及删除图书暂未支持，请理性选择）。
C++语言编写：
cpp

char where_fangwei, where_xingzhuang, where_build, where_book_count[4];
int where_hang, where_lie, where_floor, many = 0;
int out_book = 0;
} a[9999999];
