I had to do this 3 assignments I finished them I Just wanted to show it to you guys to see if there was anything I Could do to make it better or to shorten some of them Thanks =).

1. Write a subroutine (&evens) that recieves an array of numbers and returns an array containing only even numbers Give an example of calling the subroutine.

#!/usr/bin/perl

use strict;
use warnings;

my@num = (1..10);
sub even
{
foreach my$number(@num)
 {
  if ($number%2==0)
  {
   my @evens = $number;
   print "@evens";
  }
 }
}
&even

2. Write a subroutine(&squares) that recieves an array of numbers and squares each number in the array. Note: nothing is returned.

#! /usr/bin/perl
use strict;
use warnings;

my @nums = (1..10);
sub square
{
foreach my$number (@nums)
 {
   my$number = ($number * $number);
   print "$number\n";
 }
}

3. Write a subroutine(&huge) that returns true if the number sent is greater than 1,000,000 or false(look up what is true and false). Show an example of calling the function.

#!/usr/bin/perl

use strict;
use warnings;

sub huge
{
my $num = <>;
if ($num > 1000000)
{
  print "1";
}
else{
  print "0";
}
