2录入选课信息 3录入学生成绩 3按班统计学生选课情况及考试成绩。 4按课程统计学生名单及考试成绩。 5统计并输出每个同学已修学分及不及级课程。 6实现单词组合查询课程名例如输入“JAVA设计”查询可以查到如下课程 《JAVA语言与程序设计》 《JAVA程序设计》 《JAVA语言与算法设计》 注因为上面课程名中均包含“设计”和“教程”两个单词 同理输入“JAVA算法设计”查询则只能查到《JAVA语言与算法设计》 任务要求 1按照分析、设计、编码、调试和测试过程完成应用程序 2学习并使用流程图等工具并在撰写报告中使用 3程序的各项功能在程序运行时以菜单方式选择并执行 4要求用户输入数据时要给出清晰、明确的提示包括输入数据的内容、格式及结束方式等 5所有的信息存储在文件中并实现文件读写操作。 6记录添加删除操作时先从文件载入数据用链表存放批量操作完后数据从链表写入文件。 7【加分选做】根据学生的选课能够生成一个学生的课表形式与我校教务处系统中的课表相似并将时间有冲突的课程标记为红色 输入格式
提示 1学生基本信息可以设计一个结构体类型 2自己构思并增加的除规定功能之外的新功能酌情加分。
