时钟程序（C语言）怎么写
具体代码如下：

{ setcolor(GREEN); //把画笔设为绿色
circle(mid_x,mid_y,180); //钟的外圆
circle(mid_x,mid_y,150); //钟的内圆
circle(mid_x,mid_y,1); //画出钟的圆心
gettime(curtime); //取得系统当前时间
th_sec=(float)curtime.ti_sec*0.1047197551; //把秒针的角度化为弧度，为以后绘制时方便，下同

//计算出时针的尾的坐标（时针长70）
end_x=mid_x+70*sin(th_hour);

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。
