Specifications
Create a phone book program that stores and manages contact information.
Contact information is name and corresponding phone number. The program reads this
information for multiple contacts from a data file “contacts.txt” and saves them in a
suitable data structure. Once the data is stored, it allows the user to display all contacts,
add a single contact, remove a contact, update a contact, or populate more contacts
from a file called “update.txt”
It offers a menu with the following options:
1. D : Display all contacts in aphabetic order (sorted by first name)
2. A : Add a contact (user enters the name and phone number from console)
3. R : Remove a contact (user enters the name from console)
4. C: Change contact information (user enters the name and new phone number
from console)
5. U: Reads a list of contacts from the “update.txt” file into the existing database
6. Q: Quits the applications
Duplicate names are not allowed. If user tries to add a name already there, then no
overriding is done. Same for update. But the ‘C’ change function can be used to change
the phone number of an existing contact.
