蜂鸣声,直到任何输入 [英] beep sound till any input
问题描述
我想提出一个猜谜节目。所以,我要的是当用户之前psented在$ P $任何问题的话,他有30秒时间来回答。而在这些30秒我想以1秒的间隔的蜂鸣声('\\一个')。现在我想的是,这蜂鸣声应尽快用户输入任何输入停止。我创建了这个小功能产生蜂鸣声,持续30秒无效音(){的for(int i = 0; I< 30;我++){COUT<<\\ A;睡眠(1000); }
}
但我不知道在用户输入他/她的回答如何尽快停止,因为一旦我把它叫做什么可以直到它在做。
谁能给什么解决办法呢?
I am making a Quiz program. So what I want is whenever any question in presented before the user, then he has 30 seconds to answer it. And in these 30 seconds I want the beep sound ('\a') at an interval of 1 second. Now I want is that this beep sound should stop as soon as the user enters any input. I have created this small function to produce the beep sound for 30 sec void beep(){ for(int i=0;i<30;i++){cout<<"\a"; Sleep(1000); }
}
But I don't know how to stop it as soon as the user enters his/her answer because once I call it nothing can be done until its over.
Can anyone give any workaround for it?
推荐答案
免责声明:我不是一个Windows程序员,我不知道这是好作风或者即使它会编译或工作。我不能在这里进行测试。然而,由于没有其他人给出的解决方案,这是一个起点。因为我了解我将修改这个答案,并希望有人谁知道更多关于这将露面。
Disclaimer: I'm not a Windows programmer, I don't know if this is good style or even if it will compile or work. I can't test it here. However, as no one else has given a solution, it's a starting point. I'll edit this answer as I learn more, and hopefully someone who knows more about this will turn up.
修改:我伪造了 _kbhit()
来一个简单的函数返回假
,它至少编译和看起来像它运行正常。
Edit: I faked out _kbhit()
to a trivial function returning false
, and it at least compiles and looks like it runs ok
修改:好吧,我确实有MS在工作Visual Studio中,我从来没有使用它。在code,因为它是现在编译和作品(我怀疑时间结束了,虽然)。
Edit: Ok I do have ms visual studio at work, I just never use it. The code as it is right now compiles and works (I suspect the timing is off though).
修改:已更新其立即读回被打(而不是等待用户按下回车键)键
Edit: Updated it to immediately read back the key that was hit (rather than waiting for the user to hit enter).

int main()
{
time_t startTime, lastBeep, curTime;
time(&startTime);
lastBeep = curTime = startTime;
char input = '\0';
while ( difftime(curTime,startTime) < 30.0 )
{
if ( _kbhit() ) // If there is input, get it and stop.
{
input = _getch();
break;
}
time(&curTime);
if ( difftime(curTime,lastBeep) > 1.0 ) // More than a second since last beep?
{
std::cout << "\a" << "second\n" << std::flush;
lastBeep = curTime; // Set last beep to now.
}
}
if ( input )
{
std::cout << "You hit: \"" << input << "\"\n" << std::flush;
}
return 0;
}
