电子备忘录
1 系统的基本功能利用电子备忘录记录未来某时间内的待办事宜。允许查询、添加。2 要求（1）备忘信息的保存方式自己设定，尽量保证操作灵活。一条备忘信息最多允许100个汉字。备忘信息的时间设置可以精确到具体的某个日期、或者某个日期中的某个时间段、或者某个日期中的某个具体时间。可以对事件的重复出现进行设置，如每月10号取工资，6月16号到28号每天上午9：10考试等。（2）如果在添加时，该时段内已有安排则出现提示信息。（3）查询时，如果当前日期有备忘信息，自动提醒。（4）根据键盘输入的起始日期和终止日期，统计该时间段内的所有备忘信息并输出结果（包括时间和备忘信息）；统计时按照时间的先后顺序进行排序。
