title: How do I return the largest type in a list of types?
body: <p>How would I make a class template that returns the type whose <code>sizeof</code> is greater than the others. For example:</p>
  
  <pre><code>typename largest&lt;int, char, double&gt;::type;
  </code></pre>
  
  <p>That should return <code>double</code>. How would I go about doing that?</p>
