Now, I have a question on WHY index worked at all? yes, I got an error while typing $string variable(skipped the "s" in code). however, I got an output anyways?
so i went back and replicated the error so you can see it..again
my $string = 'abcdefghijk'; my %match = (bc => "Michelangelo", efg => "Raffaello",de => "Caravaggi +o",ijk => "Tintoretto",hij=>"Leonardo",); foreach $art (keys %match){ print "this is INDEX $art =>",join(',',$match{$art}),"\n", if inde +x my $tring,$art; }
Parentheses missing around "my" list at C:\Users\Alberto\Documents\NetBeansProjects\PerlProject\Perl Essen +tials\hash_ref\partial_hash_check.pl line 48 (#1) (W parenthesis) You said something like my $foo, $bar = @_; when you meant my ($foo, $bar) = @_; Remember that "my", "our", "local" and "state" bind tighter than c +omma. Use of uninitialized value $tring in index at C:\Users\Alberto\Documents\NetBeansProjects\PerlProject\Perl Essen +tials\hash_ref\partial_hash_check.pl line 48 (#2) (W uninitialized) An undefined value was used as if it were alread +y defined. It was interpreted as a "" or a 0, but maybe it was a mi +stake. To suppress this warning assign a defined value to your variables. To help you figure out what was undefined, perl will try to tell y +ou the name of the variable (if any) that was undefined. In some cas +es it cannot do this, so it also tells you what operation you used th +e undefined value in. Note, however, that perl optimizes your progr +am and the operation displayed in the warning may not necessarily app +ear literally in your program. For example, "that $foo" is usually optimized into "that " . $foo, and the warning will refer to the concatenation (.) operator, even though there is no . in your program. this is INDEX efg =>Raffaello this is INDEX de =>Caravaggio this is INDEX hij =>Leonardo this is INDEX bc =>Michelangelo this is INDEX ijk =>Tintoretto
