Re: Question about ++ and hash value

It's counting the number of times a given line appears in a file. $hash{$line}++ is incremented by 1 (set to one automagically on the first instance of $line) each time $line (well, $line minus the piece removed by chop) appears.

Any Northeastern US area jobs? I'm currently unemployed.

The keys of the hash are the lines that appear in the input (less the character removed by chop). The values are how many times each line has been encountered. -- CollegeGear.com - more than just college gear (though, yes, we have college-branded teddy bears)	[reply]
