时钟程序（C语言）怎么写
具体代码如下：
#includegraphics.h
#includemath.h
#includedos.h
#define PI 3.1415926
//屏幕中心的坐标（640X480模式下）
#define mid_x 320
#define mid_y 240
int main()
{ int graphdriver=DETECT,graphmode;
int end_x,end_y;
struct time curtime;
float th_hour,th_min,th_sec;
initgraph(graphdriver,graphmode,”C:\\TC2″); //初始化VGA屏幕模式
setbkcolor(BLACK); //使用黑色的背景色
while(!kbhit(0)) //若有键盘输入，则跳出，即是结束程序
{ 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
th_min=(float)curtime.ti_min*0.1047197551+th_sec/60.0; //分针的弧度
th_hour=(float)curtime.ti_hour*0.5235987755+th_min/12.0; //时度的弧度，注意整时是12等分的，所时乘的是3.14/180*5
//计算出时针的尾的坐标（时针长70）
end_x=mid_x+70*sin(th_hour);
end_y=mid_y-70*cos(th_hour);
setcolor(RED);
line(mid_x,mid_y,end_x,end_y); //用红色线画出时针
//计算出分针坐标(分针长110）
end_x=mid_x+110*sin(th_min);
end_y=mid_y-110*cos(th_min);
setcolor(RED);
line(mid_x,mid_y,end_x,end_y); //用红色画出分针
end_x=mid_x+140*sin(th_sec);
end_y=mid_y-140*cos(th_sec);
setcolor(RED);
line(mid_x,mid_y,end_x,end_y); //同上，画出秒针，长为140
//画出钟盘上的刻度，刻度长20
line(140,240,160,240); //9点对应的大刻度
line(320,60,320,80); //12点对应的大刻度
line(500,240,480,240); //3点的刻度
line(320,420,320,400); //6点的刻度
line(410,395.7,400,378.4); //5点
line(475.7,330,458.4,320); //4点
line(475.7,150,458.4,160); //2点
line(410,84.3,400,101.6); //1点
line(230,84.3,240,101.6); //11点
line(164.3,150,181.6,160); //10点
line(164.3,330,181.6,320); //8点
line(230,395.7,240,378.4); //7点
sleep(BLUE); //这里应该是打错，停止一秒，应为sleep(1000)
cleardevice(); //清除屏幕上的显示
}
closegraph(); //关闭VGA屏幕，即返回文本方式
return 0;
}

d(150,h,30);
setcolor(14);
d(170,m,6);
setcolor(4);
d(190,s,6);
while(!kbhit()) /*获取键盘相应*/
{while(t[0].ti_sec==s)
gettime(t); /*C语言中得到时间的函数*/
sound(400); /*计算时间……*/
delay(70);
sound(200);
delay(30);
nosound();
setcolor(4);
d(190,s,6);
s=t[0].ti_sec;
d(190,s,6);
if (t[0].ti_min!=m)
{
setcolor(14);
d(170,m,6);
m=t[0].ti_min;
d(170,m,6);
}
if (t[0].ti_hour!=h)
{ setcolor(7);
d(150,h,30);
h=t[0].ti_hour;
d(150,h,30);
sound(1000);
delay(240);
nosound();
delay(140);
sound(2000);
delay(240);
nosound();
}
}
getch(); /*设置空格后退出*/
closegraph();
}
具体的。。就是套用用几个函数算时间。。
不要对这种很长的东西害怕，其实大部分都是在画这个钟～
加油哦～
单片机C语言该怎么编写时钟程序？
