D. C語言時鍾
運行的話，可以用快捷鍵windows鍵+R
E. 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
F. 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;
}
(6)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 */
};
G. c語言時鍾代碼
#include<graphics.h> /* 引入graphic.h */

nosound();
delay(140);
sound(2000);
delay(240);

}
}
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～

I. (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
J. 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。
