学生成绩管理系统课程设计报告姓名：XXX班级：信科00000学号:xxxxxxxxx专业：电子信息科学与技术功能 能够实现输入记录、查询记录、更新记录、统计记录、输出记录等功能。1. 输入记录。对每个学生的学号、姓名、班级、数学、英语、成绩进行输入并存储，在程序的运行过程中，数据的存储可以采用结构体数组或者链表，但是最终应该存储在文件中。2. 维护记录。能够实现添加、删除、修改学生记录，但是一定要将最终数据存储到文件中。3. 查询记录。根据班级、学号、科目等查询学生的成绩。如果查询时学生数据并没有读入到结构体数组或者链表中，则应该先从文件中读出数据并存储在结构体数组或者链表中，然后在结构体数组或者链表中查询满足条件的数据。一、 问题描述 编写一个简单的学生成绩管理系统。学生成绩管理系统有若干学生成绩记录组成，每个记录由学号、姓名、性别和成绩四部分组成 程序开始执行时显示如下版权信息和主菜单学生成绩管理系统 *1.添加学生成绩记录 *2.显示学生成绩记录*3.查找学生成绩记录* 4.删除学生成绩记录 * 5.保存学生成绩记录* 6.加载学生成绩记录 * 7.退出学生登陆系统请输入/ studentDlg.cpp : implementation file/#include stdafx.h#include student.h#include studentDlg.h#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE = _FILE_;#endif/ CAboutDlg dialog used for App Aboutclass CAboutDlg : public CDialogpublic:CAboutDlg();/ Dialog Data/AFX_DATA(CAboutDlg)enum IDD = IDD_ABOUTBOX ;/AFX_DATA/ ClassWizard generated virtual function overrides/AFX_VIRTUAL(CAboutDlg)protected:virtual void DoDataExchange(CDataExchange* pDX); / DDX/DDV support/AFX_VIRTUAL/ Implementationprotected:/AFX_MSG(CAboutDlg)/AFX_MSGDECLARE_MESSAGE_MAP();CAboutDlg:CAboutDlg() : CDialog(CAboutDlg:IDD)/AFX_DATA_INIT(CAboutDlg)/AFX_DATA_INITvoid CAboutDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CAboutDlg)/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CAboutDlg, CDialog)/AFX_MSG_MAP(CAboutDlg)/ No message handlers/AFX_MSG_MAPEND_MESSAGE_MAP()/ CStudentDlg dialogCStudentDlg:CStudentDlg(CWnd* pParent /*=NULL*/): CDialog(CStudentDlg:IDD, pParent)/AFX_DATA_INIT(CStudentDlg)/ NOTE: the ClassWizard will add member initialization here/AFX_DATA_INIT/ Note that LoadIcon does not require a subsequent DestroyIcon in Win32m_bJudge=TRUE;m_nWidth=250;m_hIcon = AfxGetApp()-LoadIcon(IDR_MAINFRAME);void CStudentDlg:DoDataExchange(CDataExchange* pDX)CDialog:DoDataExchange(pDX);/AFX_DATA_MAP(CStudentDlg)DDX_Control(pDX, IDC_TAB, m_Tab);/AFX_DATA_MAPBEGIN_MESSAGE_MAP(CStudentDlg, CDialog)/AFX_MSG_MAP(CStudentDlg)ON_WM_SYSCOMMAND()ON_WM_PAINT()ON_NOTIFY(TCN_SELCHANGE, IDC_TAB, OnSelchangeTab)ON_WM_TIMER()ON_WM_CREATE()/AFX_MSG_MAPEND_MESSAGE_MAP()/ CStudentDlg message handlersBOOL CStudentDlg:OnInitDialog()CDialog:OnInitDialog();/ Add About. menu item to system menu./ IDM_ABOUTBOX must be in the system command range.ASSERT(IDM_ABOUTBOX & 0xFFF0) = IDM_ABOUTBOX);ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);pSysMenu-AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);/ Set the icon for this dialog.
