the_ID()
Display the ID of the current post in the WordPress Loop.
Post ID in the loop can be also obtained through $post->ID. Sometimes it's easier and there is no unnecessary call of the function.

No Hooks.
Return
null. Nothing (null). The post ID is displayed immediately.
Usage
<?php the_ID(); ?>
Examples
#1 Let's print the inscription "Post Number: 465" on the screen (for post 465)
<p>Post Number: <?php the_ID(); ?></p>
#2 HTML Anchor of the post
<h3 id="post-<?php the_ID(); ?>"><?php the_title(); ?></h3>
Now the link to this anchor will be: http://site.com/link_to_post#post-465
in XHTML, the id attribute of an HTML tag cannot start with a digit. Therefore, you need to add at least one letter before the_ID().
