My program is trying to read from a line and count the number of parentheses however, as you can see it's not working very well: My code runs, but does not work, as no matter what either both l_count and r_count are the same or it throws an error about the parentheses not being balanced properly...

How do I count the # of Parentheses in a string? Edit: samarzone fixed me up right and showed me what I was doing wrong. It has thus been fixed:

sub parenth { my ($string) = (@_); my $l_count = () = ($string =~ /\(/g); my $r_count = () = ($string =~ /\)/g); if ($l_count != $r_count) { print "There is no balance on this line! Did you format it + correctly???"; return 0; } else { print "There is balance in this universe"; return 1; } }
Any thoughts on how to implement such parsing methods without regex (is that even possible?)

Or just ideas in general for uses, as such?
