主要目的：实现对实验室的硬件资源和软件资源的使用和管理。 数据信息：用户登录信息（分普通成员–管理员：信息主要有用户名、密码、性别、专业班级、学号、联系电话、QQ等） 硬件器材信息（编号、名称、数量、存放地点、所属类别、主要用途） 图书资源信息（图书编号、图书名称、图书数量、图书类别、主要用途） 主要功能： 1.登录界面：实现不同用户的登录、找回密码、注册新用户。 2。普通用户登录之后功能选择：查询资源记录、借还资源、修改个人信息。 3.管理登录可以增加新的耗材记录、修改用户信息。#include<stdio.h>#include<string.h>#include<stdlib.h>#include<conio.h>struct personal_message{ //个人信息 char name[10];
