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

Maybe something along the lines of:

c:\@Work\Perl>perl -wMstrict -e "my @strings = qw(DOG COT BAL MAN); ;; use constant FMT => '%6s'; ;; printf FMT, $_ for '', @strings; print qq{\n}; ;; for my $row (@strings) { printf FMT, $row; for my $col (@strings) { my $d = diff($row, $col); printf FMT, $d; } print qq{\n}; } ;; sub diff { return scalar ($_[0] ^ $_[1]) =~ tr/\0//c; } " DOG COT BAL MAN DOG 0 2 3 3 COT 2 0 3 3 BAL 3 3 0 2 MAN 3 3 2 0

Update: In the
    sub diff { return scalar ($_[0] ^ $_[1]) =~ tr/\0//c; }
function definition, the scalar call is not needed, but does no harm. (Assignment to a scalar imposes scalar context.)

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 or How to display code and escape characters are good places to start.
