Listing all of user questions

I finally found the code that I want!
 
to list all of questions:
 
<ul>
<?php
$curauth = (isset($_GET[‘author_name’])) ? get_user_by(‘slug’, $author_name) : get_userdata(intval($author));
query_posts( array(
‘post_type’ => array(‘dwqa-question’),
‘author’ => $author )
);
?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<li>
<a href=”<?php the_permalink() ?>” rel=”bookmark” title=”Permanent Link: <?php the_title(); ?>”><?php the_title(); ?></a>
</li>
<?php endwhile; else: ?>
<p>no questions found</p>
<?php endif; ?><?php wp_reset_query(); ?>
</ul>
 
and to list answers:
 
<ul>
<?php
$curauth = (isset($_GET[‘author_name’])) ? get_user_by(‘slug’, $author_name) : get_userdata(intval($author));
query_posts( array(
‘post_type’ => array(‘dwqa-answer’),
‘author’ => $author )
);
?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<li>
<a href=”<?php the_permalink() ?>” rel=”bookmark” title=”Permanent Link: <?php the_title(); ?>”><?php the_title(); ?></a>
</li>
<?php endwhile; else: ?>
<p>no answers found</p>
<?php endif; ?><?php wp_reset_query(); ?>
</ul>
