I have to use some data structure to store a contact list ie a list of names and the corresponding phone numbers.
What would be the most suitable data structure ?
I have been thinking about a SortedMap, Set, vector etc ...

My main operations on this contact list would be to update it from another Master contact list.

Thanks !
