in reply to factorial through recursion

Here's something that might work:
#factorial through recursion use strict; use warnings; print "enter number\n"; my $num=<>; my $fac = &fact($num,1); print "factorial: $fac\n"; ################## sub fact { my($num1,$flag)=@_; if($num1==0) { return $flag; # print "$flag" and die "brrrrrrrreeeeeee :D\n"; } else {fact($num1-1,$num1*$flag);} }
It's good (better/best) to use return statement in recursive code!
Also, instead of shift, use @_
