If you need to pass multiple arrays to a subroutine, you need to use array references - see
perlref,
perlretut,
perllol and/or
perldsc. It might look something like:
#!/usr/bin/perl
use strict;
use warnings;
my @arrays = (
[1,2,3],
[6,32,6,87],
[2,456,56,7,3324,6,4365],
);
iterator(@arrays);
sub iterator
{
for my $array_ref (@_) {
my $avg = average(@$array_ref);
print "Your average is $avg\n"
}
}
sub average
{
my @stuff = @_;
my $sum = 0;
($sum+=$_) for @stuff;
my $average = $sum / @_;
return $average;
}
