Counting the Times Two Unknown Values Appear Togetherby Dru (Hermit)
|on Jul 15, 2007 at 02:44 UTC||Need Help??|
Dru has asked for the
wisdom of the Perl Monks concerning the following question:
I am trying to count the number of times an unknown value appears on the same line as another unknown value. When I say "unknown" I mean I do not know beforehand what the value will be, so I can't match it using a regex or something, but I do know the position of these values on the line.
I created a hash reference (I believe this is what this data type is called) that saves the data that I want, but haven't been able to figure out the counting piece.
Referring to my snippet of code below, I would like to count the number of times $sport appears on the same line as $src in a file
The file is rather large, so I would prefer not to process it twice.
