Hello,

I am implementing a function for add or subtract variable value according to button pressed time.

When i press button for a short time it should increase or decrease 0.1 from variable. When i press button for 4-5 second, it should increase or decrease 1 from variable. When i press button more then 8 second, it should increase or decrease every time 10 from variable.

Code: 
float x = 0.01
while(a < 200)
{
	if(DownKey) 
	{
		k -= x;
		a = 0;
	}	
	if(UpKey) 
	{
		k += x;
		a = 0;
	}	
	if(k > 99.99) k = 99.99;
	if(k < 0) k = 0;
	delay_10ms();
	a++;
}

My concern is, how can i set X in 0.1, 1, 10 format according to button pressed time?

{
  keypressed++;
  switch (keypressed)
  {
     10: 
        x = 0.1;
        break;
     20: 
        x = 1
        break;
     // etc.
  }
}
else
{
  keypressed = 0;
  x = 0.01;
}
