计算机高级语言课程设计报告 学生成绩管理系统（MFC）班级：201131学号：20131000349姓名：马瑞琪日期：2013年1月17号一 课程设计题目与要求 （1）增加记录：要求可以连续增加多条记录。（2）删除一个学生的记录：要求可以先查找，再删除。删除前，要求用户确认。（3）成绩修改：若输入错误可进行修改；要求可以先查找，再修改。（4）查找：可以根据姓名（或学号）查找某个学生的课程成绩，查找某门课程成绩处于指定分数段内的学生名单等等。（5）排序功能：要求按总分进行排序（从高到低），若总分相同，则按数学排序；若总分和数学相同，则按物理排序；若总分和各科成绩都相同，则按学号排序； （7）文件操作：可以打开文件，显示班级的所有学生信息；可以将增加或修改后的成绩重新写入文件；可以将排序好的信息写入新的文件。 二 需求分析利用MFC来实现这一程序，需要定义一个数组，来贮存学生的信息，并且这个数组在整个程序里面都要能够用到。 实现录入这个功能，需要添加一个列表控件，并且对列表进行初始化，设置列表的风格和大小。实现添加这个功能，需要增加几个列表的控件变量，来接受要添加的新的学生信息。实现修改这一功能，需要用添加的几个控件变量来接受要修改的信息，并且储存在数组中，然后将修改后的信息显示在列表上。实现排序这一功能，需要把数组中的数进行比较，然后将排完序的成绩显示在列表上。实现删除这一功能，需要把删除的那个人用下一个人的信息把这个人的信息代替，然后显示在列表中。三 概要设计主界面退出排序删除修改查找录入该程序有六大模块：1. 录入模块；2. 查找模块；3. 修改模块；4. 删除模块；5. 排序模块；6. 退出模块； 四 详细设计1：界面设计源代码BOOL CMyDlg: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.
