1、第一題：1,【實驗題目及要求】問題描述設計一個程序，記錄并管理日程計劃。基本要求(1)日程計劃信息包括日程計劃ID號，日程計劃開始日期和時間，日程計劃結束日期和時間，日程計劃名，日程計劃參與人員，日程計劃地點，日程計劃提醒日期和時間。(2)采用雙向循環(huán)鏈表表示日程計劃信息。采用三個雙向循環(huán)鏈表：第一個雙向循環(huán)鏈表表示未開始的日程計劃信息，按照日程計劃開始日期和時間先后排序；第二個雙向循環(huán)鏈表表示正在進行的日程計劃信息(可以多項計劃同時進行)，按照日程計劃開始日期和時間先后排序；第三個雙向循環(huán)鏈表表示已過期的日程計劃信息，按照日程計劃開始的日期和時間倒序排序。(3)日程計劃信息采用文件方式輸入。

2、日程計劃信息信息示例如下，每條信息一行：日程計劃ID號開始日期開始時間結束日期結束時間計劃名20141011001;2014-10-11;8:00:00;2014-10-11;10:00:00;數(shù)據(jù)結構上課;張三；6202;2014-10-11;7:40:00(4)要求模擬數(shù)據(jù)中日程計劃信息至少30條以上。(5)實現(xiàn)以下功能：a.輸入新的計劃；b.根據(jù)當前時間查詢未開始的計劃，包括當天未開始的計劃、本周或本月未開始的計劃；c.查詢并輸出已結束的計劃；d.查詢正在進行的計劃；e.根據(jù)當前時間，輸出正提醒即將開始的計劃。(6)可在此要求基礎上進行功能擴展，比如周期性重復計劃的設置和提醒等。2,【源
