用C语言编一个数码管时钟显示程序
问题不太清楚，想帮也无从下手呀！单片机用的是哪款？时间数据哪里来？是程序的一部分还是整个程序就这么点功能？10S报时是语音报时还是“滴滴滴”声报时？“最后一位是10MS，也就是说整个循环是100S”何意？
本人在用C语言编一段三位一体数码管动态显示程序，求高手指点
如果你的硬件已连接完善，那编程需：
1、动态扫描：在已个 t 时间内（可以是几个ms）选中 1 位数码管，以亮点该位数码管对应的码段，其他关断（不亮）；而下一个 t 时间需点亮下一位数码管......以此类推，循环起来。这个 t 可以用定时器准确控制。当然，如果你只是为了实现单纯的3个数码管显示，可以不精确时间，循环起来就是了（只要保证耽搁的显示时间少于肉眼识别时间，就是看起来不会一闪一闪的就行）；
2、显示内容：多数情况下，待显示的字符/数字先按数码定义编码，存放在表格中。按自己的编程需要，在显示的时候从表格中提取。当然，如果只是简单实验，显示的内容是固定的，也可以程序里用立即数。
多试一试吧。

用C语言编一个数字电子时钟的程序
1.这是用windows api写的程序。所以要求是纯c的话就没有办法了
2.其中定时用了两种方法。一种是用取消息。另一种是延时队列。这里只使用了取消息的方法。延时队列由于我机器上是vc6.0，CreateTimerQueue在本人机器上无法使用，需要新的sdk，所以没有加以验证，但取消息的方式是可行的。
3.稍稍验证了下，基本满足要求。

下面是纯c的。
有几个问题：
1.textmode函数在turboc中没有办法使用，不知道是什么问题，而borland c就可以。
2.无论怎么设置，自己的ctrlbreak函数在上述两个环境中都不能被调用，非常遗憾。所以不能够优雅的退出。只能按两次ctrlbreak。
