用C語言編一個數字電子時鐘的程序
1.這是用windows api寫的程序。所以要求是純c的話就沒有辦法了
2.其中定時用了兩種方法。一種是用取消息。另一種是延時隊列。這裡只使用了取消息的方法。延時隊列由於我機器上是vc6.0，CreateTimerQueue在本人機器上無法使用，需要新的sdk，所以沒有加以驗證，但取消息的方式是可行的。
3.稍稍驗證了下，基本滿足要求。

下面是純c的。
有幾個問題：
1.textmode函數在turboc中沒有辦法使用，不知道是什麼問題，而borland c就可以。
2.無論怎麼設置，自己的ctrlbreak函數在上述兩個環境中都不能被調用，非常遺憾。所以不能夠優雅的退出。只能按兩次ctrlbreak。
