I have a method here that should work for you. The first thing we'll do is create a subroutine that checks for existance of an item in an array. Then we'll loop over every element in Array1 and check for it's existance in Array2. The code looks like:

sub in_array{ my $value = shift; my @array = @_; foreach $item (@array){ if($value eq $item){ return 1; } } return 0; } @array1 = ("q", "w", "e", "r", "t","z"); @array2 = ("q", "w", "e", "r", "t","y"); foreach $value (@array1){ if(!in_array($value,@array2)){ print "Value $value does not match any value in \@array2\n"; } }

This should output exactly what you want. Enjoy.

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.
