Hello,
I create a hash, and i want take the keys.
Using Deitel Book, i take this example:
numbers =
(
1 => 'one',
3 => 'two',
5 => 'three',
7 => 'four',
9 => 'five',
);
@hashkey = keys (%numbers);
When I try to run come this message.
Undefined subroutine &main::chaves called at line
What's wrong ?
Would "chaves" mean "keys"?
my @haskeys = keys %numbers;
I think the parens were telling Perl to look for a sub named "keys". I
could be wrong...and frequently am.
my %numbers =
(
1 => 'one',
3 => 'two',
5 => 'three',
7 => 'four',
9 => 'five',
);
my @hashkey = keys %numbers;
