( #3333=superdoc: print w/replies, xml ) Need Help??

I'm not too sure what your code is supposed to be doing. It looks a bit like you're trying to count the number of times a particular value occurs in an array. The normal way of doing this is to use a hash:

#!/usr/bin/perl use warnings; use strict; my @ID = qw/1 1 1 1 1 1 1 2 2 2 2 2 3 3 4 4 4 4 5 5 5 5 6/; my %counts; foreach my $id (@ID) { $counts{$id}++; } while(my ($num, $count) = each(%counts)) { print "$num : $count\n"; }

But you might be trying to do something more complicated than that. Some more explanation of what you're trying to achieve would help

It's not easy to juggle a pregnant wife and a troubled child, but somehow I managed to fit in eight hours of TV a day.

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
