title: C++ variable types limits
body: <p>here is a quite simple question(I think), <strong>is there a STL library method that provides the limit of a variable type</strong> <em>(e.g integer)</em> <strong>?</strong> I know these limits differ on different computers but there must be a way to get them through a method, right?</p>
  
  <p>Also, <strong>would it be really hard to write a method to calculate the limit of a variable type?</strong></p>
  
  <p>I'm just curious! :) </p>
  
  <p>Thanks ;).</p>
