c语言钟表
⑴ c语言编写钟表的问题
#include<graphics.h>
#include<math.h>
#include<dos.h>
#define PI 3.1415926
#define x0 320 /*定义钟表中心坐标*/
#define y0 240
void DrawClock(int x,int y,int color) /*画表盘*/
{ int r=150; /*表盘的半径*/
float th;
setcolor(color);
circle(x,y,r);
circle(x,y,2);
}
void DrawHand(int x,int y,float th,int l,int color)
{
int x1,y1;
x1=x l*sin(th);
y1=y-l*cos(th);
setcolor(color);
line(x,y,x1,y1);
}
void main()
{int gdriver=DETECT,gmode;
struct time curtime;
float th_hour,th_min,th_sec;
initgraph(&gdriver,&gmode,"");
setbkcolor(0);
while(! kbhit())
{
DrawClock(x0,y0,14);
gettime(&curtime); /*得到当前系统时间*/
gotoxy(35,20); /*定位输出位置*/
if((float)curtime.ti_hour<=12) /*午前的处理*/
{printf("AM ");
if((float)curtime.ti_hour<10) printf("0"); /*十点之前在小时数前加零*/
printf("%.0f:",(float)curtime.ti_hour);
}
else /*午后的处理*/
{printf("PM ");
if((float)curtime.ti_hour-12<10) printf("0");
printf("%.0f:",(float)curtime.ti_hour-12);
}
if((float)curtime.ti_min<10) printf("0");
printf("%.0f:",(float)curtime.ti_min);
if((float)curtime.ti_sec<10) printf("0");
printf("%.0f",(float)curtime.ti_sec);
/*以下三行计算表针转动角度，以竖直向上为起点，顺时针为正*/
th_sec=(float)curtime.ti_sec*0.1047197551; /*2π/60=0.1047197551*/
th_min=(float)curtime.ti_min*0.1047197551 th_sec/60.0;
th_hour=(float)curtime.ti_hour*0.523598775 th_min/12.0; /* 2π/12=0.5235987755 */
DrawHand(x0,y0,th_hour,70,2); /*画时针*/
DrawHand(x0,y0,th_min,110,3); /*分针*/
DrawHand(x0,y0,th_sec,140,12); /*秒针*/
sleep(1); /*延时一秒后刷新*/
cleardevice();
}
closegraph();
}
能正常运行,我测试过

⑵ 用C语言做数字时钟每走一秒响一次，求大神告诉源代码
“响一次”需要牵涉到图形编程中的音乐播放问题，需要自己下载图形编程相关库文件，具体实现请自己在TODO里添加播放音乐的代码
数字时钟的实现很简单，运用time.h相关函数即可
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
time_toldt=-1;
structtm*p;
boolPrintdate()
{
time_tt=time(NULL);
if(t!=oldt)
{
oldt=t;
p=localtime(&t);
system("cls");
printf("%d/%d/%d周",1900+p->tm_year,1+p->tm_mon,p->tm_mday,p->tm_hour,p->tm_min,p->tm_sec);
switch(p->tm_wday)
{
case1:printf("一");break;
case2:printf("二");break;
case3:printf("三");break;
case4:printf("四");break;
case5:printf("五");break;
case6:printf("六");break;
case7:printf("日");break;
}
printf("%d:%02d:%02d",p->tm_hour,p->tm_min,p->tm_sec);
return1;
}
return0;
}
main()
{
while(1)
if(Printdate())
{
/*************TODO*************/
/**Forexample:printf("a");**/
}
return0;
}
