No operator matching those operands
<p>I'm also receiving the 'no operator "&lt;&lt;" matches these operands" error while trying to display the information.</p>

<pre><code>    cout &lt;&lt; (&lt;- error with these) PrintHex(ASphere.CalcCircumference()) &lt;&lt; endl;
</code></pre>

<p>I looked around and most people state that it's because of a missing #include. However I think I have everything I need to include. (it also doesn't become a problem until I try to display the info from the functions.)</p>

<pre><code>#include &lt;iostream&gt;
#include &lt;iomanip&gt;
#include &lt;string&gt;
</code></pre>

<p>My function looks like this.</p>

<pre><code>void PrintHex(int InNum)
{
cout &lt;&lt; hex &lt;&lt; setiosflags (ios_base::showbase) &lt;&lt; InNum;
};
</code></pre>
