Restrict "whats on" category to show from my home page

Hi,

I have a blog in which on home page all the latest posts are displaying.

I want to restrict “whats on” category from displaying there.

This is my code:

`if ( get_query_var(‘paged’) ) { $paged = get_query_var(‘paged’);

} elseif ( get_query_var(‘page’) ) { $paged = get_query_var(‘page’);

} else { $paged = 1; }

query_posts( array( ‘post_type’ => ‘post’, ‘paged’ => $paged ) );

$num=0; if (have_posts()) : while (have_posts()) : the_post(); $num++;`

I WANT TO SHOW ALL THE CATEGORIES IN LATEST POST, JUST 1 CATEGORY TO RESTRICT.
