 If you want to create a newspaper site or blog site like newspaper you need to display post base on category. Here I will add a WordPress snippets which will display category name by Category ID.

Category name with category link by ID

The above two snippets will display Category name and category link separately by category id. I only added the above two codes as a link.
<a href="<?php echo get_category_link(4); ?>"><?php echo get_cat_name(4);?></a>

A small project of above snippets

Simply add the below WordPress snippets where you want to display post from specific category. If your sidebar widgets support php code, You can add it into you sidebar using text widgets.
<h2><a href="<?php echo get_category_link(4); ?>"><?php echo get_cat_name(4);?></a></h2>
<ul>
  <?php
	$catquery = new WP_Query( 'cat=4&posts_per_page=10' );
	while($catquery->have_posts()) : $catquery->the_post();
	?>
  <li> 
    <a href="<?php the_permalink() ?>" rel="bookmark">
     <?php the_title(); ?>
    </a>
  </li>
