You can use action hook and enqueue script and style to the site.

function my_scripts() {
    wp_enqueue_style('bootstrap4', 'https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css');
    wp_enqueue_script( 'boot1','https://code.jquery.com/jquery-3.3.1.slim.min.js', array( 'jquery' ),'',true );
    wp_enqueue_script( 'boot2','https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js', array( 'jquery' ),'',true );
    wp_enqueue_script( 'boot3','https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js', array( 'jquery' ),'',true );
}
add_action( 'wp_enqueue_scripts', 'my_scripts' );

If you want to add the scripts after jQuery then you can use the jQuery array for dependent and last argument true will include the JS at footer, if you want the js in header, you can remove that.
