pre, samp, code

[Pieter Provoost]

Hi,

I'm trying to display some c++ code (without using &gt that contains this
line:

#include <string>

I tried <pre>, <samp>, <code> and <pre class="code">, but the only thing
that works is the deprecated <xmp>. In all other case the <string> is not
displayed. Are there any better solutions?

Thanks!
Pieter

The < and > characters in will always (at least in IE) be used as HTML tags.
If those tags are not valid, it won't be displayed either.

Your solution to the problem is to convert it to the following:

#include &lt;string&gt;

If you're using PHP to display code samples, you can use the function
htmlentities():

Why can't you use &gt; and &lt;? This is the proper way.

Yes, xmp is quite old. <code> would be best.

The only proper way to do it is to replace instances of < and >, there's
no good reason why you can't do this.

You could also save the c++ code as a text file and embed it with an
iframe or <object> construct, but this is a flawed method.

Why are you trying to avoid the correct way to achive this?

that contains this line:

#include <string>

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

You need to convert the reserved characters to entities.

The only proper way to do it is to replace instances of < and >,
there's no good reason why you can't do this.

To be exact, the ">" character can be written as such. It's just a common
habit to present it as &gt; for symmetry. There's no reason why a browser
should treat ">" as anything but a data character when it is processing
element content (as opposite to processing a tag after having encountered
a "<" character that starts a tag).
