Hi there,
I am stuck with something here.
What does the following piece of code mean?
my @temp1;
my @temp2;
$cnt=0;
$temp2[$cnt] = [@temp1];
What is the kind of data stored in $tempFieldNames[$information] ?
Your creating a reference to an array as and storing that reference in array
index 0.
Data::Dumper can be very helpful for understanding what's going on here its
no different than doing saying $temp2[$cnt] = \@temp1;
#!/usr/bin/perl -w
use strict;
use Data::Dumper;
my @temp1 = ("Apple", "Orange", "Mango");
my @temp2;
my $cnt=0;
$temp2[$cnt] = [@temp1];
print Dumper(\@temp2);
$VAR1 = [
[
'Apple',
'Orange',
'Mango'
]
];
As you can see here the first element index 0 in your array contains an
anonymous array.
I hope this is clear.
Please help.
