Other monks have given you some good answers to your question above, but I wanted to point out an error in your code in case it wasn't a typo. In your C-ish style loop:

for (my $x = 0; $x < $#arr; $x++) {} # ^^^^^^^
the condition you're using will prevent the loop from running for the final array element, because you only enter the loop when the counter is strictly less than the last index of the array. To correct it, simply change to one of these:
for (my $x = 0; $x <= $#arr; $x++) {} # ^^ # up to *and including* the last index for (my $x = 0; $x < @arr; $x++) {} # ^ # when used in scalar context, '@arr' returns the number of # elements in @arr

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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.
