How Can i Get 5 Recent Post Title With Corresponding Link?

I Want to Add My Latest 5 Post Title with Corresponding Link in My Header Position.What was the Actual Php code?Am Newbie ….

This sounds like an additional Loop on that page, right?
You might want to use:

<ul>
    <?php $posts_query = new WP_Query('posts_per_page=5');
        while ($posts_query->have_posts()) : $posts_query->the_post();
    ?>
    <li><a href="https://wordpress.stackexchange.com/questions/20489/<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
    <?php endwhile; wp_reset_query(); ?>
</ul>
