Is there a way to ask user for input but after a certain time do somethin else if they don't give input
for example:

C#

while (true)
{
    if (d.Key == ConsoleKey.UpArrow)
    {
        v--;
    }
    if (d.Key == ConsoleKey.DownArrow)
    {
        v++;
    }
    if (d.Key == ConsoleKey.RightArrow)
    {
        h++;
    }
    if (d.Key == ConsoleKey.LeftArrow)
    {
        h--;
    }
  -------- if no input after 1 second
    { do something }
}

Solution 1

Create a thread that checks for keyboard activity every X seconds. If the thread doesn't detect activity, do something. When the user kits a key, set a value indicating the datetime of the activity. This is the variable that the thread would check to see how long it's been since the last activity.

Go forth, and code.

5 from a cp noob. Even I do not agree with your solution to the end. The thread should signal timeout and nobody has to scan/check.

C#

while (true)
  {
    if (d.Key == ConsoleKey.UpArrow)
    {
       v--;
    }
    else if (d.Key == ConsoleKey.DownArrow)
    {
       v++;
    }
    else if (d.Key == ConsoleKey.RightArrow)
    {
       h++;
    }
    else if (d.Key == ConsoleKey.LeftArrow)
    {
       h--;
    }
    else
    {
      //Starting a timer
      Timer tmr = new Timer(ComputeBoundOp, 5, 0, 2000); 
      Thread.Sleep(10000); // //Executing other works over here (10 seconds)
      tmr.Dispose(); // Cancel the timer now

    }
}

            interval = DateTime.Now - startTime;
        else
            interval = stopTime - startTime;

        return interval.TotalSeconds;
    }
    // sample usage
    public static void Main(String[] args)
    {
        StopWatch s = new StopWatch();
        s.Start();
        ConsoleKeyInfo d = Console.ReadKey();
        while ("CONDITION HERE")
        {
            if (d.Key == ConsoleKey.UpArrow)
            {
                Console.WriteLine("key pressed ");

            }
            if (s.GetElapsedTimeSecs() < 1)
            {
                s.Stop();
                Console.WriteLine("Do something else ");
            }
