title: How to implement a timer with interruption in C++?
body: <p>I'm using the GCC compiler and C++ and I want to make a timer that triggers an interruption when the countdown is 0. </p>
  
  <p>Any Ideas? Thanks in advance.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Thanks to Adam, I know how to do it.</p>
  
  <p>Now. What about multiple timers running in parallel?</p>
  
  <p>Actually, these timers are for something very basic. In NCURSES, I have a list of things. When I press a key, one of the things will change colors for 5 seconds. If I press another key, another thing in the list will do the same. It's like emphasize strings depending on the user input. Is there a simpler way to do that?</p>
