如何用C语言编辑一个闹钟！求高手！

Answer 1

呵呵，写了一个玩玩：
#include <stdio.h>　　唯让
#include <windows.h>　　
#include <winbase.h>　

int main(int argc, char *argv[])
{
SYSTEMTIME time;
SYSTEMTIME clock;
GetLocalTime(&time);
printf("当前时间为：%2d:%2d:%2d\n",time.wHour,time.wMinute,time.wSecond);

printf("请设早闹定闹陆山罩钟时间：\n");
printf("时：");
scanf("%2d",&clock.wHour);
printf("分：");
scanf("%2d",&clock.wMinute);

while(1)
{
Sleep(1000);
GetLocalTime(&time);

if((time.wHour==clock.wHour)&&(time.wMinute==clock.wMinute))
{
printf("\a\a\a时间到!!!");
break;
}
}

return 0;
}

Answer 2

#include <windows.h> /* vc 环境下,如果是linux更简单你上网查alarm,sleep这两个函数*/
#include <stdio.h>

int main()
{
int sec;
printf("请输入缓瞎要设置的秒数哗闹:"扰芦空);
scanf("%d",&sec);
printf("等待....\n");
sleep(sec);
printf("时间到\n");
return 0;
}
