[C++知识库]C++ 课设 高校人员信息管理系统

前言

🎬本文章是 【C++笔记】 专栏的文章，主要是C++黑马的笔记、自己的实验与课设

问题描述

某高校有四类员工：教师、实验员、行政人员、教师兼行政人员

1. 共有的信息：编号、姓名、性别、年龄
2. 教师的信息：所在系部、专业、职称
3. 实验员的信息：所在实验室、职务
4. 行政人员的信息：政治面貌、职称

功能要求

1. 添加功能：程序能够任意添加上述四类人员的记录，可提供选择界面供用户选择所要添加的人员类别，要求员工的编号要唯一，如果添加了重复编号的记录时，则提示数据添加重复并取消
2. 添加查询：功能可根据编号、姓名等信息对已添加的记录进行查询，如果未找到，给出相应的提示信息，如果找到，则显示相应的记录信息
3. 显示功能：可显示当前系统中所有记录，每条记录占据一行
4. 编辑功能：可根据查询结果对相应的记录进行修改，修改时注意编号的唯一性
5. 删除功能：主要实现对已添加的人员记录进行删除。如果当前系统中没有相应的人员记录，则提示“记录为空！”并返回操作；否则，输入要除的人员的编号或姓名，根据所输入的信息删除该人员记录，如果没有找到该人员信息，则提示相应的记录不存
6. 统计功能：能根据多种参数进行人员的统计。例如：统计四类人员数量以及总数，或者统计男、女员工的数量，或者统计某年龄段人员的数量等
7. 保存功能：可将当前系统中各类人员记录存入文件中，存入方式任意
8. 读取功能：可将保存在文件中的人员信息读入到当前系统中，供用户进行使用

测试数据

基本功能均已实现，东西挺多的就不附测试结果了。因为编写数据也挺麻烦的，仓库中每类人员各编写了五个，直接把txt中的数据粘贴到运行窗口

问题总结

上面代码放的是正确的，在此之前有另外一个版本，在每次读取完文件退出主程序时，跳转xutility发生读写权限冲突，因为string对象维护的是一段内存，而读入二进制文件保存的是内存地址，在下一次读取时这段内存地址发生变化，所以出现错误。解决办法，将四个人员类中的变量定义为char类型的数组。仓库也保存了一份string编写的源码，想看错误可以直接下上跑一下

参考：C++类对象进行文件读取后出现的xutility错误

解决string类型读写问题后，代码没有报错但是一旦运行检索类的功能，出现变量堆栈损坏，首先考虑的是数组中输入的字符超过了定义的长度，所以各个char类型长度要合理定义，查了一下果然是这个问题
