I am trying to read in a file. The structure of the file is city:country. What I need to do is to show cities within a country. My thought was to read the file into a hash, with it like this:

US:Miami
US:New York
US:Chicago

I understand that an @ array basically uses a number as the identifier of the value. How does a hash do it?
