title: How do you "break" out of a function?
body: <p>Given a function that returns a value, is it possible to exit the function given a certain condition without returning anything?  If so, how can you accomplish this?</p>
  
  <p>Example:</p>
  
  <pre><code>int getNumber ()
  { 
      . . . 
  }
  </code></pre>
  
  <p>So say you are in this function.  Is there a way to exit it without it doing anything?</p>
