Array vs List output

[Neeraj]

Hi,

I am new to Perl and perplexed with output of printing entire Array vs
printing each element

    +4  ## check Array vis-a-vis List
    +5
    +6  @arr = qw <hello happy new year 2013>;
    +7  print "my array is : @arr \n";
    +8
    +9  ## lets print in a loop
   +10  my $i = 0;
   +11  while ($i <= $#arr)
   +12  {
   +13   print $arr[$i];
   +14   $i += 1;
   +15  };
   +16  print "\n";


I expected the output of printing Array in line 7 to be same as printing
each element.
However, output of line 7 is : hello happy new year 2013
while printing each element: hellohappynewyear2013

Why do i have white-space between words when printing array while not
getting white-space when printing individual element.

Thanks,
Neeraj
