设计一个具有菜单式界面（可使用控制台程序，以可选条目方式呈现；也可使用VC图形界面）的课程管理系统，其中包括

 　　课程类和学生类，例如，课程类包括：课程编号、课程名、授课教师、上课时间（春季学期或夏季学期）、上课地点、学时数、学分、（是否）限选专业等属性；学生类包括：学号、姓名、年级、专业等数据属性。

 　　学生可以根据某一门课程是否为该生所属专业限选/可选，以及上课时间、上课地点等信息来合理确定选课表（比如平均处理各学期的所修学分和学业负担，某一上午连续两门课的上课地点不宜过远，以避免课间10分钟内无法达到导致迟到等等），一旦课程被选定，相应选修该门课程的人数就更新，每门课程有选课人数上限，一旦到达上限人数，则不允许再被学生选课

 　　不同年级/专业的学生限选课程数目不同。待选课信息要能为所有学生浏览。

你可根据你在湖大选课系统的相关操作完善上述需求描述，你更可以添加人性化的操作，比如预约下学期课程，前提是要为课程增加相关数据成员。

本项目可能涉及的OO内容包括（但不限于）：类与对象、复合、静态成员、继承、多态等。相关数据保存及可能的读写操作均在文本文件或binary文件中进行，不涉及数据库。
