Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.

C++ please help me answer this question I will give you a good rating Thank you! Explain Public VS Protected VS Private Explain the difference between public, protected and private headers in a class. Be specific. HINT: Who can access the different members?
please code c++ please and please dont just copy from others pretty please A. Create an abstract base class called Currency with two integer attributes, both of which are non-public (Python programmers - it is understood that there is nothing private in Python but try to not access the attributes directly from outside the classes). The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part. B. Create two derived classes - Krone and Soum - with one additional non-public string attribute which will contain the name of the currency (Krone or Soum) respectively. DO NOT add this attribute to the base Currency class. C. In your base Currency class, add public methods for the following, where appropriate (C++ students are allowed to use friend methods as overloads only, i.e. the corresponding class method needs to be defined first): Default Construction (i.e. no parameters passed).…

C++ please help me answer this question I will give you a good rating Thank you! Explain when to implement the Big Three. Explain your answer above about which classes need the Big Three in the question above both why they are needed and why not. Explain Public VS Protected VS Private Explain the difference between public, protected and private headers in a class. Be specific. HINT: Who can access the different members?
Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
