Subject: Use a hash or multi dimensional array?
DISCLAIMER: I'm new to programming other than a little bit of scripting for cron jobs.
I'm parsing a comma delimited file for a specific 2 letter code on each line in the
file. Once I find that 2 letter code I want to increment a count value and store it.
I've thought about putting it into a 2 dimensional list that would hold the 2 digit
code and a count. So every line I process would look for that 2 letter and the count
value. If it finds it, read it in along with the count value. Increment the count
value. Remove the old count along with the 2 letter code using a pop. Then push the
new value and 2 letter to the list.
The only reason I keep looking at a hash is because I need to sort the list when I do
my reporting.
I thought about taking the cheesy way out and use a case/switch setup, but I won't
always know what the 2 letter codes will be.
