Asterisk in function type : <p>I found some code online for a <a href="http://www.taywils.me/2014/11/15/boostchatclient.html" rel="nofollow noreferrer">C++ Chat Server</a>. And in the code below contains something I don't get</p>

<pre><code>string* buildPrompt()
{
// Code for chat server
}
</code></pre>

<p>What is that asterisk after <code>string</code>? If I remove it, will the code stop working?</p>
