I want to produce a radio button like this:
<input type="radio" name="quest0" value="a" required>
I am doing like this
echo form_radio("quest0","a");
But how can I add required attribute using Codeigniter form helper.

I think you can do it this way.(I did not tested it)
$data = array(
'name' => 'quest0',
'value' => 'a',
'required' => 'required'
);
echo form_radio($data);

Try this:
<input type="radio" name="myradio" value="1" <?php echo set_radio('myradio', '1', TRUE); ?> />
<input type="radio" name="myradio" value="2" <?php echo set_radio('myradio', '2'); ?> />

One way is to write as shown by @Shaiful Islam.
Other way is to write as below:
echo form_radio("quest0","a", FALSE, "required=required");
Refer the Source Code - Form Helper - Line 459
You are passing the other parameters as EXTRA attribute

You can add other attributes like id, data-*, required in 4th parameter of form_radio() function, try this code
echo form_radio("quest0","a", false,"required id=\"quest0\"");

Girish, 3rd Parameter must be a BOOLEAN value. TRUE or FALSE. Refer the [source code] (github.com/bcit-ci/CodeIgniter/blob/develop/system/helpers/…). Am assuming that the question is related to CI Version 2.0

sorry, you right, i forgot 3rd parameter for
form_input(), and form_select, form_radio() function get element attribute in 4th parameter
