呵呵，写了一个玩玩：
#include
#include
#include
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("请设定闹钟时间：\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;
}
