What is the output of this WordPress loop code snippet?

Consider this WordPress loop snippet inside a theme template:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
  <h2><?php the_title(); ?></h2>
<?php endwhile; else : ?>
  <p>No posts found.</p>
<?php endif; ?>

If there are no posts published, what will this code output?

A A PHP error will occur because the_post() is called without posts.

B Nothing will be displayed on the page.

C <h2></h2> repeated for each post.

D <p>No posts found.</p>

💡 Hint

Look at the else part of the if statement.

If no posts exist, the else block runs and outputs <p>No posts found.</p>.

Why does this WordPress shortcode not display content?

Given this shortcode function in functions.php:

function my_shortcode() {
  return 'Hello, world!';
}
add_shortcode('greet', 'my_shortcode');

When you add [greet] in a post, nothing appears. What is the likely cause?

A The theme does not call <code>the_content()</code> to process shortcodes.

B The shortcode is not registered because add_shortcode is missing a priority argument.

C The shortcode function must echo, not return, the string.

D Shortcodes only work in widgets, not in posts.

💡 Hint

Shortcodes need to be processed inside the content output.

If the theme does not use the_content() function to display post content, shortcodes won't be processed and will not show output.
