I have a stupidly basic question. In Perl if you declare a variable do you have to specifically intialize it? For example if I want to use the variable 'i' in my while loop. 
my $i;
while ($i<5)
{
$i++;
}

[download]
will 'i' automatically be set to zero and incremented from there or do I have to say my $i=0; Is it a similar case with the ".=" on non-intialized vars?
Thanks.
