Question

Design a C++ program

An address book is a book or a database used for saving and storing contacts which may usually
consists of a few standard fields (for example: first name, last name, company name, address,
telephone number, e-mail address, fax number, mobile phone number).
Design an online address book to keep track of the details of family members, close friends and
certain business associates. Details which your designed address book will keep should be like
names (first name, last name), gender, addresses (street address, city, province/state, zip code),
phone numbers, and dates of birth (date, month, year). Your program should be able to handle a
maximum of 150 entries.
There should be TWO MAJOR MODULES of your program one should allow the user to add, update
delete the entries and classify the entered person as a family member, friend, or business associate
and another module should maintain one address book which must be able to process a maximum
of 150 entries and also should perform the following operations:
 Load the data into the address book from a disk.
 Search for a person by last name.
 Print the gender, address details, phone number, and date of birth of a given person.
 Print the names of the people whose birthdays are in a given month or between two given
dates.
 Print the names of all the people having the same status, such as family, friend, or
business.
 Print the names of all the people having the same status, such as family, friend, or
business.
 Print the names of all the people between two last names.
 Print the details of all people with same gender.
