As friends said above, its otherwise called as associative
array. It has lot of advantages over perl.
Here we can keep the values in a structured way, that
structured way comes from key-value pairs.
Eg: (The syntax given above are also correct, but the below
representation is much better in look and feel)
my %hash_example = ( a => 10,
b => 20,
c => 30 );
keys : a,b,c
values : 10,20,30
Features of Hash :
##################
1) Keys should always be unique where as values may not be
unique
(Right)
my %hash_example = ( a => 10,
b => 10,
c => 10 );
(wrong)
my %hash_example = ( a => 10,
a => 20,
a => 30 );
2) keys (%hash_example) will return an array containing only
keys
my @keys = keys(%hash);
3) similary for values
my @values = keys(%values);
