post title links to category archive

Dear WordPressers,

I would like that my post titles on my index page link to my category archive. (Optimally I would want to use an anchor that jumps to the right post on the category archive…)

So, I am trying to find out what code outputs the post title but links to the category archive.

I was trying this code
<h2 class="post"><a href="<?php the_category() ?>" title="<?php the_title(); ?>"></a></h2>
but it outputs this
# Category ” title=”title”>

Anyone willing to help me? Be very much appreciated!
