Hi All,
I am trying to declare variables(hash ref) dynamically in a loop
I wanna use the name of hash ref as the value of string.
For eg:
my $i=0;
foreach my $k ( sort keys %$headers) {
$$i={}; >>>>>>> creating hash ref with the value
of $i i,e hash name should be $0
print "> ref($$i) <";
$$i{$k} = $rows[$i];
push (@input_data, $$i);
$i++;
}
On a whole I am trying to create hash ref data-structures and finally want
to populate in an array.
but the program does'nt allow me to declare a hash like this $$i={};
Throws an error "Modification of a read-only value attempted "
Also tried to use hash rather than hash ref
34 my $i=0;
35 my $x=1;
36 foreach my $k ( sort keys %$headers) {
37 %$x=(); #>> used hash instead
38 # print "key: $k \n";
39 $$x{$k} = $rows[$i];
40 print "Now Assigned: $$x{$k} : Org is $rows[$i]
>>>>>>>>>>>>>>>>>>> $i <<\n";
41 $i++;
42 }
43 print ">>>>>", Dumper(%$x),"<<<<<<\n"; exit; #
THIS DOESNT HAVE THE HASH VALUES AT ALL
44 push (@input_data, \%$x);$x++;
Please advice
Thanks & Regards
Neetee
