桌面模擬時鍾c語言程序加註釋

『壹』 C語言 電子時鍾源代碼程序 帶圖 謝謝 最好有注釋

#include <stdio.h>

#include <time.h>

#include"stdlib.h"

#include "windows.h"

void main ()

{

while(1)

{

time_t rawtime;

struct tm * timeinfo;

time ( &rawtime );

timeinfo = localtime ( &rawtime );

printf ( "07The current date/time is: %s", asctime (timeinfo) );

Sleep(1000);

system("cls");

}

}

『貳』 誰能幫我用c語言編寫桌面鍾表啊！
