用C语言怎么编辑一个闹钟？

呵呵，写了一个玩玩：\x0d\x0a#include \x0d\x0a#include \x0d\x0a#include 　\x0d\x0a\x0d\x0aint main(int argc, char *argv[])\x0d\x0a{\x0d\x0aSYSTEMTIME time\x0d\x0aSYSTEMTIME clock\x0d\x0aGetLocalTime(&time)\x0d\x0aprintf("当前时间为：%2d:%2d:%2d\n",time.wHour,time.wMinute,time.wSecond)\x0d\x0a\x0d\x0aprintf("请设定闹钟时间：\n")\x0d\x0aprintf("时：")\x0d\x0ascanf("%2d",&clock.wHour)\x0d\x0aprintf("分：")\x0d\x0ascanf("%2d",&clock.wMinute)\x0d\x0a\x0d\x0awhile(1)\x0d\x0a{\x0d\x0aSleep(1000)\x0d\x0aGetLocalTime(&time)\x0d\x0a\x0d\x0aif((time.wHour==clock.wHour)&&(time.wMinute==clock.wMinute))\x0d\x0a{\x0d\x0aprintf("\a\a\a时间到!!!")\x0d\x0abreak\x0d\x0a}\x0d\x0a}\x0d\x0a\x0d\x0areturn 0\x0d\x0a}

该程序已在Turbo

C++3.0中通过编译.

呵呵，写了一个玩玩：

#include <stdio.h>

#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

}
