博主最近面临SWUST的C++课设作业，我们是有3个题目选择的：电梯控制系统程序设计、学校人员信息管理系统和个人银行账户管理系统。本来想直接用上一届师兄的课设-----电梯控制系统程序设计，但看到题目要求说有可视化界面加大分，但是师兄的并未包含这个内容，所以就自己做一个吧，毕竟我也想要把分数搞高一点呀，哈哈！
但是在这里还是把师兄的课设放在这里供大家参考吧！

学校人员信息管理系统
操作演示
OK啦，我们直接看下效果好吧
由于完整操作视频转为GIF图后较大，无法直接写入本博客，想要查看完整演示的可以看下面这个
QT学校人员管理系统
MP4转GIF动图
在这里也给大家安利一波MP4视频文件转GIF动图的方法吧，可以说是百试不爽啦
首先安装 moviepy
pip install moviepy听说有时安装会报错，由于我之前把默认下载源改为清华镜像源的了，所以这里并未出现任何报错，如果大家有安装报错的也可以尝试用镜像源安装，如下：
pip install moviepy -i https://pypi.tuna.tsinghua.edu.cn/simple接下来输入以下代码进行转换
from moviepy.editor import VideoFileClipdef convert_mp4_to_gif(input_file, output_file, fps=10):# 使用with语句确保clip在使用后自动关闭with VideoFileClip(input_file) as clip:# 将视频转换为GIFclip.write_gif(output_file, fps=fps)if __name__ =='__main__':input_file = "E:\Desktop\Qt.mp4" # 替换为你的MP4文件路径output_file = 'qt.gif' # 输出的GIF文件路径convert_mp4_to_gif(input_file, output_file)设计功能要求
（1）包括一个基本的人员信息类，人员信息有编号、姓名、性别、年龄等，允许用户进行以下操作:开户、销户、登陆；用户登陆后可以查看相关信息。
（2）人员管理管理系统包括教师学生两部分，学生又分本科生和研究生。
（3）教师类在人员信息类基础上新增职称和部门等数据信息，新增功能：①输入并保存教师信息；②教师用户登陆后可以查看相关信息。
（4）学生用户登陆后可以查看各门课相关信息（包括成绩、在已输入学生中的成绩排名）。
（5）由教师类和学生类派生一个研究生类，新增研究方向和导师等数据信息，新增功能：①输入并保存信息；②研究生用户登陆后可以查看相关信息。
（6）将所有用户信息存于文件中。
评分标准

| 可视化方式实现，难度值加分（10~20分） 控制台实现，难度值加分（1~10分） |
可以看到哈，可视化界面和控制台两种方式连打的基础分都不一样，所以可视化特别重要呀
QT Creator安装和新建项目
可视化界面的实现一定是离不开QT软件的呀，这里给大家简单介绍一下QT的安装和使用方法吧！
QT安装
下载地址：Index of/archive/qt/
官方地址：https://www.qt.io/download-open-source
这里我以官方地址为例，大家根据电脑配置选择合适的即可
QT的安装需要注册，大家按照安装流程正常操作即可
这里选择上面那个，接着一路下一步即可
由于我之前已经安装过QT软件，所以这里可能会继承我之前选择的一些内容，大家如果有步骤和上面不一样（或者需要选择组件的话），可以按照下面的组件选择
QT新建项目
创建项目 - > Application(Qt) - > Qt Widgets Application
这里的名称和路径都可以自定义
这里选择qmake
这里的名称可以自定义，注意：Generate form一定要勾选（不然后面运行会报错）
这里我只有一个组件，如果大家遇到有多个的话，直接全部勾选即可
最后会生成对应的 .h 、.cpp 以及 .ui 文件

mainwindow.h 程序释义
这个文件大家主要关注4个点就可以咯，其他的都是QT实现的功能（非重点）
class Person：基本的人员信息录入
class Teacher : public Person：教师新增信息录入，职称和部门
class Student : public Person：本科生信息录入，语数英3科成绩（排名后面会自动排序）
class Graduate : public Person：研究生新增信息录入，研究方向和导师
void savePeopleInfoToFile(const QString &filename = "people_info.txt")：filename是最后保存的txt文件路径
此外，下面这个是该 .h 文件包含的C++课设考察内容，具体是哪一部分大家需要自己查看

}mainwindow.cpp 程序释义
这个部分我自己写了一个详细的界面释义，大家感兴趣的可以看一下
此外，为了呈现出的可视化效果更好，我在初始界面又增添了图片展示
// 图片路径自己更改即可
QPixmap pixmap("F://QT_code//Manage//image.jpg");同样的，这个部分的课设考察内容如下：
/********************************实现默认参数值的函数。使用引用。实现内联函数。定义类的构造函数和析构函数。使用动态创建的数组或vector模板。实现继承与派生以及多态。使用文件流。********************************/
main.h 文件
// main.cpp
#include <QApplication>
#include "mainwindow.h"int main(int argc, char *argv[])
{QApplication a(argc, argv);MainWindow w;w.show();return a.exec();
}/************************************************实现目标：默认形参值的函数。引用的知识。内联函数。丰富的数据类型。正确定义类，类中构造函数、析构函数完整，数据访问属性明确。静态数据、常数据。指针的正确使用。动态创建数组或vector模板的应用。继承与派生正确使用，多态。文件流的使用。************************************************/
大家直接运行 main.h 文件就可以实现全部内容啦！
TXT文件生成
该TXT文件会在点击退出键时保存所有未销户的人员信息，并不会产生覆盖，也就是说重复操作时都只会保存在这一个文件上。
总结：这个课设基本上全部实现了功能要求并且达到了评分标准，但就是可视化出的界面太丑咯呀，大家后面可以在该基础上添加背景和字体颜色这些美化的东西哦。至此，本次的C++课设就全部完成啦，希望对大家的课程设计能够有所帮助呀！
这篇关于C++课程设计：学校人员信息管理系统（可视化界面）的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
