Hi Monks,
For many of you, this will be pretty simple, yet I'm having some problems putting this into code. I'm reading in a file.
open(IN, "<$file") || die "Can't open $file!\n";
while(<IN>) {
chomp($_);
my ($id, $stdate, $enddate, $person) = split(/\|\|/, $_);
}
There is a many to many relationship between $id and $person. I want to produce a list that has a count of id's for each person. It seems a hash would be the most likely way to do this. But I haven't been able to get it to work. Here is what I would like to produce for the output:
James P 24 id's
Alex S 50 id's
Diane G 4 id's
James A 12 id's
Sam D 11 id's
Any thoughts?
Louis
