in reply to printing elements of an array on new lines

Anonymous Monk,

print "$_\n" for @array;

Cheers - L~R

Update: I love Perl

In a short span of time numerous solutions have been provided. For such a simple task as printing the elements of an array - lots of Perl has been used:

  • bare blocks to limit scope
  • The need to use local instead of my on Perl built in global variables
  • printf for flexibility over print
  • Print many with a for loop versus printing once with join
  • Weird built in variables such as $_, $", $/, and $,

    Let me add a couple more using $\ and map 

    {
    local $\ = "\n";
    print $_ for @array;
}

or

print map {$_ .= "\n"} @array;

      Re this snippet:

      print map {$_ .= "\n"} @array;

      As the OP is obviously a beginner, I believe that the proviso to this, namely that it changes @array (adding a newline to each element), should be clearly stated.

        dave,
        You ever start typing a word and end up automatically type something else out of habit? That should have been: 
        print map {$_ . "\n"} @array;
