Hi all, straight out of the Learning Perl book (3rd edition, page
275) is this code:
my @numbers;
push @numbers, split while <>;
foreach (sort { $a <=> $b } @numbers) {
printf "%20g\n", $_;
}
This works flawlessly. My question is why can't I put that
variable declaration in the push function? like this:
push my @numbers, split while <>;
foreach (sort { $a <=> $b } @numbers) {
printf "%20g\n", $_;
}
Because the push() statement is in a loop, and my() would empty
the variable at each iteration.
