Hello All,

I have two arrays contains exact no. of elements. Now what I need to do
is , I want to execute certain commands to each elements of the array at
a time.

It means that I want take first element of first array and first element
of second array and then want to execute certain commands considering
these two elements.

I don't know how should I achieve this in perl.

In addition to the answers already received, you could take advantage
of the List::MoreUtils module from CPAN:

#!/usr/bin/perl
use strict;
use warnings;
use List::MoreUtils qw/zip natatime/;

my @foo = (1, 2, 3);
my @bar = qw/a b c/;

my $it = natatime 2, zip(@foo, @bar);
while (my ($f, $b) = $it->()) {
print "$f - $b";
}
__END__

1 - a
2 - b
3 - c

If we're buying into List::MoreUtils then I feel it's more explicit to use each_array to create the iterator. You're also missing a newline in your print statement.

use strict;
use warnings;

use List::MoreUtils qw/each_array/;

my @foo = 1 .. 3;
my @bar = 'a' .. 'c';

my $it = each_array(@foo, @bar);

while (my ($f, $b) = $it->()) {
print "$f - $b\n";
}
.
