C++ online address book

Using classes students will create an online address book. It will store the following information:

• Peoples names

• Addresses

• Phone numbers

• Date of birth

• Contact Relationship status (friend, family, business) •

Should be able to handle 100 entries You will create the following classes:

• personType

o will be able to set, get, and print a person’s first and last name

• contactType

o will be derived from personType

o contain a dateType and addressType objects

o will be able to set, get, and print: birth date phone number address and contact relationship status (friend, family, business)

o all values will be initialized using constructors

o will have functions that are overridden from the base class

• dateType

o will be able to set and get dates o functions will provide error checking for appropriate date formats

• addressType

o will be able to set and get : street address city state zip o all values will be initialized using constructors

• addressBookType

o can process up to 100 entries

o loads data from a file

o sorts address book by last name

o search for person by last name

o print address, phone number, date of birth of a given person

o print names of people whose birthdays are in a given month

o print the names of all the people between 2 last names

o print names based on a query (i.e. all family members, or friends, or business associates
