C语言辅助学习系统
本次毕业设计重点介绍了C语言辅助学习系统、网上考试系统和在线交流模块的实现过程：包括系统分析、系统调查、数据流程分析、功能设计、数据库设计、系统的运行环境、系统测试及调试。本系统主要面向两类人员使用：管理员（教师）、普通学生，他们拥有不同的权限。考试模块使用的过程是管理员添加试题，制订出题规则，生成试卷。学生登录后选择要考的试卷然后进入答题，完毕后提交试卷，存入数据库并评分。系统管理员可以查询考生的成绩，每个考生只能查询自己的成绩。辅助学习系统模块，管理员添加辅助学习文档，并对文档进行分类、修改等操作，而普通用户只能浏览内容。在线交流模块中，任何用户都可以登录留言，管理员可以删除留言。另外总结了本系统的特点：节约辅助学习成本，提高考试工作的效率。
