① 怎樣用c語言編寫時鍾（轉的那種）
純c怕是寫不出來，會用到其他東西吧，如win32界面編程、mfc，openCV，dx。
如果樓主是為了完成作業才弄什麼時鍾，下面的就不用看了
要是為了興趣，幹嘛去弄時鍾，弄鍵盤鉤子、視頻監控，遠程攝像頭多好玩。
最近在看這書：Visual+C++典型模塊與項目實戰大全，裡面有很多好玩的項目
② c語言時鍾代碼
#include<graphics.h> /* 引入graphic.h */
#include<math.h> /* 引入math.h */
#include<dos.h> /* 引入dos.h */
#define pi 3.1415926 /*定義pi=3.14159*/
#define X(a,b,c) x=a*cos(b*c*pi/180-pi/2)+300;
#define Y(a,b,c) y=a*sin(b*c*pi/180-pi/2)+240;
#define d(a,b,c) X(a,b,c);Y(a,b,c);line(300,240,x,y) /*定義……*/
void init() /*初始化程序*/
{int i,l,x1,x2,y1,y2; /*定義……*/
setbkcolor(1); /*設置顏色*/
circle(300,240,200); /*作園*/
circle(300,240,205);
circle(300,240,5);
for(i=0;i<60;i++) /*循環（算時間）*/
{if(i%5==0) l=15;
else l=5;
x1=200*cos(i*6*pi/180)+300;
y1=200*sin(i*6*pi/180)+240;
x2=(200-l)*cos(i*6*pi/180)+300;
y2=(200-l)*sin(i*6*pi/180)+240;
line(x1,y1,x2,y2);
}
}
main()
{
int x,y;
int gd=VGA,gm=2;
unsigned char h,m,s; /*定義*/
struct time t[1];
initgraph(&gd,&gm,"d:\\tc");
init();
setwritemode(1);
gettime(t);
h=t[0].ti_hour;
m=t[0].ti_min;
s=t[0].ti_sec; /*定義時分秒*/
setcolor(7); /*設置顏色*/
d(150,h,30);
setcolor(14);
d(170,m,6);
setcolor(4);
d(190,s,6);
while(!kbhit()) /*獲取鍵盤相應*/
{while(t[0].ti_sec==s)
gettime(t); /*C語言中得到時間的函數*/
sound(400); /*計算時間……*/
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(); /*設置空格後退出*/
closegraph();
}
具體的。。就是套用用幾個函數算時間。。
不要對這種很長的東西害怕，其實大部分都是在畫這個鍾～
加油哦～
③ c語言中怎麼設置計時器
#include <iostream>
#include <time.h>
using namespace std;
int main()
{
clock_t start = clock();
//do some process here
clock_t end = (clock() - start)/CLOCKS_PER_SEC;
cout<<"time comsumption is "<<end<<endl;
}
(3)c語言時鍾擴展閱讀
使用linux的系統設置計時器
#include <sys/time.h>
int main()
{
timeval starttime,endtime;
gettimeofday(&starttime,0);
//do some process here
gettimeofday(&endtime,0);
double timeuse = 1000000*(endtime.tv_sec - starttime.tv_sec) + endtime.tv_usec - startime.tv_usec;
timeuse /=1000;//除以1000則進行毫秒計時，如果除以1000000則進行秒級別計時，如果除以1則進行微妙級別計時
}
timeval的結構如下：
strut timeval
{
long tv_sec; /* 秒數 */
long tv_usec; /* 微秒數 */
};
④ c語言怎麼樣編寫一個時鍾程序

⑤ (100分)c語言寫時鍾
不相信你.
點(sin x),( cos x) (0<x<360) 在直角坐標系中能構成一個圓.
line(x1,y1,x2,y2) point(x,y) 是常用的畫線和點的函數,自己做吧

⑨ C語言怎樣編時鍾那個東西，程序
讀取系統時間，將其轉換為你想表現的樣子，static控制項上 自繪表盤 或者 電子時鍾LED顯示 等等。然後設置個定時器 每秒更新一次
⑩ C語言時鍾
運行的話，可以用快捷鍵windows鍵+R
