in reply to String Variables ....

Strange, I changed your code slightly to allow a test run without the Wordnet modules and it works, see below. It might be a problem with WordNet

#!/usr/bin/perl
use warnings;
use strict;

my $Infile1 = shift;
my $Infile2 = shift;

open (INPUT, "$Infile1") || die "can't open the input file1";
chomp (my @words1 = <INPUT>);
close (INPUT) ;

open (INPUT, "$Infile2") || die "can't open the input file2";
chomp (my @words2 = <INPUT>);
close (INPUT) ;

for my $i (0 .. $#words1) {
if ($words1[$i] =~ /\#n$/){
    for my $j ( 0 .. $#words2) {
         if ($words2[$j] =~ /\#n$/){
             my $value = getRelatedness("$words1[$i]#1", "$words2[$j]#
+1");
 
  print "similarity of $words1[$i] and $words2[$j] = $value\n";}
}}}

sub getRelatedness { print join(':',@_),"\n"; return 4; }


OUTPUT:
July#n#1:July#n#1
similarity of July#n and July#n = 4
July#n#1:Macdonough#n#1
similarity of July#n and Macdonough#n = 4
Macdonough#n#1:July#n#1
similarity of Macdonough#n and July#n = 4
Macdonough#n#1:Macdonough#n#1
similarity of Macdonough#n and Macdonough#n = 4

    could not be because of wordnet since when i put the string in getrelatedness it gives me correct answer

      So... if:

        my $value = $measure->getRelatedness("cat#n#1", "dog#n#1");

      [download]
      works, but:
        my $value = $measure->getRelatedness("$words1[$i]#1", "$words2[$j]#1
+");

      does not, then whatever "$words1[$i]#1" and "$words2[$j]#1" yield, it isn't what you think it is. The trick is to check, carefully, looking out for odd things like stray CR or even LF characters... I suggest:
        sub show {
    my ($s) = @_ ;
    $s =~ s/([\x00-\x1F\x7F-\xA0])/sprintf("\\x%02X", ord($1))/eg ;
    return $s ;
  } ;

      [download]
      and then add replace your print statement with:
        print "similarity of '", show("$words1[$i]#1"), "' and '", show("$wo
+rds2[$j]#1"),
           "' = $value\n";

      [download]
      and check whether anything "odd" shows up.

        Flexible alternative: 

        use Data::Dumper;

sub show {
    my ($s) = @_ ;
    local $Data::Dumper::Indent = 0;
    local $Data::Dumper::Terse = 1;
    local $Data::Dumper::Useqq = 1;
    return Dumper($s);
}

        And you don't need to add quotes anymore: 

        print "similarity of ", show("$words1[$i]#1"),
      " and ",          show("$words2[$j]#1"),
      " = $value\n";
