Return Value

Following is the example code showing its basic usage −

$retval = Sum(5,10);
print ("Return value is $retval\n" );

@retval = Sum(5,10);
print ("Return value is @retval\n" );

sub Sum($$){
   my($a, $b ) = @_; 

   my $c = $a + $b;
   return($a, $b, $c);

When above code is executed, it produces the following result −

Return value is 5 10 15
