perl hash ref create
To create a Perl hash reference, you can use the curly braces {}
to define an anonymous hash and assign it to a scalar variable. Here's an example:
my $hash_ref = {
key1 => 'value1',
key2 => 'value2',
key3 => 'value3'
};
In this example, $hash_ref
is a scalar variable that holds a reference to the anonymous hash. You can access the values of the hash using the arrow operator ->
. For example, to access the value associated with key1
, you can use $hash_ref->{key1}
.
Please note that the code provided is a basic example, and you can add more key-value pairs to the hash as needed.
