what you probably want is:

<?php 
echo '<a href="CourseDetails.php?code=' . $code . 
     '&term=' . $term . '&year=' . $year. 
     '&course=' . $row_Grad['c_code'] .
     '>' . $row_Grad['c_code'] . '</a>';
?>

although I might have misunderstood and you may not want 
	'&course=' . $row_Grad['c_code'] .
as you may want to leave course blank.

To set course to blank, just don't mention it.  It's not particularly
easy to set it explicitly to empty string in a GET string.  This is why
you often see code like:

if(defined $code && $code ne "")
{
}

although that's Perl, and the semantics in PHP may be subtly different.

If this doesn't answer the question post more code and include your
error messages

All the best,
