設計要求: (1). 在 1-- 8樓之間一次可輸入多個任意樓層號連續控制電梯按指定樓層號順序上升與下降.以上過程完成后可重新輸入任意樓層號連續控制電梯按指定樓層號順序上升與下降.只有按ESC鍵才退出程序返回DOS狀態。例如 : 1-3-5-7-6-4-2-1 (可觀察教十樓電梯的實際運行情況). (2). 在 1 -- 7 樓之間按任意順序不連續控制電梯上升與下降. 按一次計算機鍵盤的上箭頭電梯上升一樓,按一次計算機鍵盤的下箭頭電梯下降一樓. (上箭頭的ASCII碼19H , 下箭頭的ASCII碼1AH . ) (3). 在電梯上升與下降過程中,要顯示出 1--7 樓之間所要到達的樓層數,同時還要用箭頭顯示電梯是上升狀態還是下降狀態. (4). 電梯運行到指定樓層后,打開電梯門，然后關門繼續運行. (5). 電梯運行時, 在任意時刻遇到緊急情況時應能實時中斷電梯運行.也可以在任意時刻恢復電梯運行.(按A/a 鍵模擬中斷發生,電梯停止運行.按B/b 鍵恢復電梯運行) (6). 在計算機屏幕上將電梯的平面模型改成三維立體模型. (7). 在電梯旁畫一個小方塊.這個小方塊隨電梯上升而上升,下降而下降.以增加電梯運行時的動感.

一道程序編譯順序的考題，涉及到函數調用的先后順序及運算符號的優先級等問題。下面我展開給你講。 C的程序編譯總是從main函數開始的，這道題的重點在“fun（（int）fun（a+c,b）,a-c）） ”語句。 系統首先要確定最外層 fun()函數的實參，第一個參數的確定需要遞歸調用fun()函數（不妨稱其為內層函數）。內層函數的兩個參數分別為x=a+b=2+8=10、y=b=5,執行函數體x+y=10+5=15,于是得外層函數的參數x=15。其另一個參數y=a-c=2-b=-6,再次執行函數體,得最終返回值x+y=15+(-6)=9。
