<h2><font color="#009999">21.5 Obtaining Run-Time Typing
	Information (RTTI)</font></h2>
<font size="+1">

<p>2 common ways to obtain the dynamic type of an object:</p>

<ol>
	<li><i>dynamic cast</i> - for casting <i>down</i> the inheritance
		hierarchy, checking for success</li>
	<li>Using the <tt>type_id</tt> operator to compare a dynamic type
		to a known type</li>
</ol>

<p><font color="#009999">Warning:</font> use virtual methods instead of RTTI
	and complex conditionals</p>
