As of CodeIgniter 2.x CI_ prefix is added to all core classes. Check the Change Log.

Added CI_ Prefix to all core classes.

For CodeIgniter 2.x

load->view('index_view');
    }

    function hello()
    {
        $this->load->view('hello_view');
    }

}

For CodeIgniter 1.x

load->view('index_view');
    }

    function hello()
    {
        $this->load->view('hello_view');
    }

}

Hope this helps you. Thanks!!
