generating HTML that depicts C++ code

Is there a program that generates nicely formatted HTML that depicts C++ code?

i.e. I have a C++ code fragement that looks like:
    void userCode(Fred& x, Fred& y)
    {
      x = y;   // Could be self-assignment if &x == &y
    }
   
And the program should generate the following HTML:
<tt><br>
&nbsp;&nbsp;&nbsp;&nbsp;<br>
&nbsp;&nbsp;&nbsp;&nbsp;void&nbsp;userCode(Fred&amp;&nbsp;x)<br>
&nbsp;&nbsp;&nbsp;&nbsp;{<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;x&nbsp;=&nbsp;x;&nbsp;&nbsp;&nbsp;</tt><em>//&nbsp;Self-assignment</em><tt><br>
&nbsp;&nbsp;&nbsp;&nbsp;}
</tt>

I suppose the main issues is you have to force spaces (&nbsp) for all indents and do a line break (<br>) for each line.

If anyone knows of a utility that is already out there, it would be most helpful.

Simply embrace the C++ code with the <pre> HTML tag.

<pre>
void userCode(Fred& x, Fred& y)
{
    x = y;   // Could be self-assignment if &x == &y
}
</pre>
