In my quest to improve QuizTaker.pl, I am trying to modify it, so that it can
accept questions that are a combination of multiple choice and true/false. What I
need to accomplish this (I think), is to be able to read the length of array that is
the value of a key within a hash. I have a small test function below, but it doesn't
quite work. It merely gives the memory address of the array. Any suggestions?
#!/usr/bin/perl -w
use strict;
 
my @value1=(1,2,3,4);
my @value2=(5,6);
my @value3=(7,8,9,0);
 
my %Hash = (Key1=>\@value1,Key2=>\@value2,Key3=>\@value3);
my @hasharraylengths=();
my $length = 0;
 
foreach my $key (keys %Hash){
  $length = $Hash{$key};
  push @hasharraylengths, $length;
}
 
my $l = @hasharraylengths;
for(my $x=0;$x<$l;$x++){
  print"Length of Value: $hasharraylengths[$x]\n";
}

In the end, there can be only one!
