218 second assignment
Write a program that implements something like an address book, using a
hash table to store data for rapid retrieval.
The program should interact with the user, and allow two operations:
(a) Add new data to the "address book", asking the user to enter a name and address,
and adding them to the internal data structures. (b) Looking up
a name and finding the associated address, asking the user to enter only
the name.
You may use linear probing to resolve any hash-value clashes.
