Incremental numbers in PerlScript

Hi,

Can someone please tell me how I can get incremental numbers by using
variables in PerlScript, i.e the result should be for example 01, 02,
03, etc.?

Not sure where your problem is. Many ways, e.g. even a trivial "(1..3)".
If you want to print them in a specific format like e.g. with a leading 0
then check out printf().

Here's one way:

for my $n (0 .. 99) {
my $formatted_n = sprintf "%02d", $n;
print $formatted_n, "\n";
}


See the documentation for sprintf for more info. If you just want to
print out the values you might use printf. I used sprintf in case
you wanted to use them internally, say perhaps as part of a hash key.
