Hi guys,
In the example below I create a hash with names as values and phone numbers as keys:
my % phoneDirectory=(
‘Shirly’=>‘7267975’,
‘Michael’=>‘5243755’,
‘Fred’=>‘1294874’,
);
I can extract the phone number of say Shirly by phoneNumber=$phoneDirectory{"Shirly"};
What if Shirly had more than one number. Is there a way to extract all her phone numbers by using her name as a key?
Now,Suppose I have the following file:
John Marry
John Lea
John Paul
David Patrik
David Sam
I want to be able to read the file into a has of hash and I want to be able to retrieve all elements under a key. For example I want to be able to say print $hash{John} and get Marry, Lea, Paul.
Is that possible?
