   Get Categories of Current Post
   Get a list of current post’s categories:

   
   <?php the_terms( $post->ID, 'category', 'categories: ', ' / ' ); ?>
   

   The output of the above code could be: categories: TV / Speaker / Monitor

I just wanted to add that the above piece of code will output the categories as href links.

E.g. Output of the code:

<?php the_terms( $post->ID, 'category', 'categories: ', ' / ' ); ?>

will be in the form:
categories: TV / Speaker / Monitor
