How do you "break" out of a function?
<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>
