Pull Two Different Post Types into Different HTML Containers on the Same Page

Updated 10 hours later: enriched with alternative solution and complemented with comments.

<?php
/* ******* Built-in post type "Post" ******* */
$arguments_for_posts = array(
    'numberposts' => 1, // number of posts to get
    'post_type'   => 'post' // post type
);

// get the array of post objects
$posts = get_posts( $arguments_for_posts );

// iterate through array to get individual posts
foreach( $posts as $post ) {
    // Enclosing block having unique ID
    echo '<article id="post-' . $post->ID . '">';
        // Post title (property of $post object)
        echo '<h1>' . $post->post_title . '</h1>';
        // Post content (property of $post object)
        echo $post->post_content;
    echo '</article>';
}

/* ******* Custom post type "Feature" ******* */
$arguments_for_features = array(
    'numberposts' => 1,
    'post_type'   => 'features'
);

$features = get_posts( $arguments_for_features );

foreach( $features as $feature ) {
    echo '<article id="feature-' . $feature->ID . '">';
        echo '<h1>' . $feature->post_title . '</h1>';
        echo $feature->post_content;
    echo '</article>';
}

Or you can use two WP_Queries when loops will look more familiar:

<?php
/* ******* Built-in post type "Post" ******* */
// Arguments
$args = array(
    'posts_per_page' => 1,
    'post_type'      => 'post',

);
// The query
$query_posts = new WP_Query( $args );

// The loop
while ( $query_posts->have_posts() ) {
    $query_posts->the_post();
?>
    <article id="post-<?php the_ID(); ?>">
        <h1><?php the_title(); ?></h1>
        <?php the_content(); ?>
    </article>
<?php
} // END while()

// Essential!
// Set the post data back up
wp_reset_postdata();

/* ******* Custom post type "Feature" ******* */
$args = array(
    'posts_per_page' => 1,
    'post_type'      => 'feature',

);

$query_features = new WP_Query( $args );

while ( $query_features->have_posts() ) {
    $query_features->the_post();
?>
    <article id="feature-<?php the_ID(); ?>">
        <h1><?php the_title(); ?></h1>
        <?php the_content(); ?>
    </article>
<?php
} // END while()
?>

Thanks @Qaisar Feroz for the useful reminder.
