Question

In the perl, how to reference values in the array of hashmap ? for example,

my %person1 = (
id => 3,
name=> 'George',
age => 29,
);

my %person2 = (
id => 3,
name=> 'George',
age => 29,
);

my @persons = ( \%person1, \%person2 );
print $persons[0]->id;  #wrong

Answer 1

You need to indicate that id is a hash key. Try

print $persons[0]->{id};
