C++学籍管理系统课程设计报告(含代码)

1、摘要：学籍管理信息系统是高校管理的重要组成部分，为老师、同学提供存档、查询等手段。根据教学安排，我们有两周的时间进行学籍管理信息系统课程设计，我们小组团结一心，分工明确，积极讨论，终于在组员的努力下及老师的指导帮助下，我们顺利完成了本次课程设计，系统包括学生资料设置，成绩设置，成绩、排名查询，修改资料关键字：系统查询课程设计论文管理-1-目录第一章绪论（1）1.1课程设计背景11.2课程设计目的11.3课程设计思路1第二章系统总体规划（2）2.1前期准备22.2系统功能2第三章系统分析设计（3）3.1建立MFC主界面及代码设计33.2学生资料设置及代码设计103.3学生成绩设置及代码设计193

3、学生管理的效率，节约教育经费，这也是适应学校信息化建设发展趋势的重要因素。因此我们有必要开发学籍管理信息系统。1.2 课程设计目的全面系统的学习面向对象程序设计的基本概念、基本语法和编程方法。正确理解掌握C+面向对象程序设计的基本特性：类、对象、继承与派生、多态、虚函数、模板、流类库等。遵循软件过程的各个环节进行系统分析、设计、实现、集成、测试，并相应给出软件规格说明书等制品。了解当前常用的软件开发工具（VisualC+乍，要求熟练掌握基于MFC勺程序设计，培养解决实际问题的能力。1.3 课程设计思路实现学生基本情况的录入、修改、删除等基本操作；能实现学生成绩的录入、修改、删除等基本操作；能方

4、便的对学生的各个学期成绩进行统计；能具有成绩统计、排名等功能；可行性分析由于本系统管理的对象单一,都是在校学生，且每个数据内容具有较强的关联性，涉及的计算过程不是很复杂。-3-第二章系统总体规划2.1前期准备学习C+6.0课本理论知识，查找、搜集相关资料，讨论出具体思路、方法，在整个过程中周老师给了我们必不可少的许多指导，使我们能够顺利地完成前期各项工作。2.2系统功能基于系统需求分析，该系统具有以下基本功能：用户管理：管理系统操作人员，设置操作人员账号、密码、用户资料等。用户资料：学生通过登录，可以查询到自己的资料、成绩、排名，同时可以修改密码。成绩管理：管理员根据学生成绩保存到系统中，同时

5、可计算出综合排名、平均分等信息。功能图登录系统I管理员登陆查询成绩排名平均分设置成绩基础数据管理：维护学生资料，主要包括院系、专业设置，联系方式、学号等个人信息设置等。学生登录查询用户资料修改密码第三章系统分析设计3.1建立MFC主界面及代码设计#include"stdafx.h"/头文件#include"学生信息管理系统.h"#include"学生信息管理系统Dlg.h"#include"xueshengziliao2.h"#include"xueshengziliao1.h"#include
