/*
在编译程序之前,请先启动mysql服务器(命令为 sudo mysqld_safe &),然后再登录mysql客户端(命令为 mysql -u root -p)建立数据库 stu;建立数据表reader,book;详细操作语句如下:
create database stu;
create table reader(stu_name varchar(20),stu_phone varchar(15),stu_password varchar(10),stu_num int,debt float,lend_time double,back_time double,count int);
create table book(book_name varchar(40),book_aut varchar(40),book_pre varchar(40),book_num int,book_mux int,book_con int);
编译时用如下命令:
g++ $(mysql_config --cflags) 110.cpp -o t $(mysql_config --libs)

程序导读:
1.程序中对书旳操作,可通过书名,编号来进行,flag=0按书名来操作,flag=1按书编号来操作
2.程序中对顾客旳操作,也可通过姓名,顾客ID号或编号两种方式来进行,flag=0按姓名来操作,
flag=1按顾客ID号或编号来操作
3.本程序分5个部分,详细已标识如(1)图书管理...
4.本程序即可实现将数据保留至当地即stu.txt,book.txt,又可将数据保留至mysql数据库,只
需稍加修改,详细怎样修改,在此就不做阐明
