Find the file /var/www/html/main/new folder/application/controllers/welcome.php and edit the syntax as below.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Welcome extends CI_Controller {
/**
* Index Page for this controller.
*
* Maps to the following URL
* http://example.com/index.php/welcome
