Question

Objectives:

1. Classes and Data Abstraction?2. User-defined classes?3. Implementation of a class in separate files

Part 1:

In this assignment, you are asked:

Stage1:?Design and implement a class named memberType with the following requirements:

An object of memberType holds the following information: • Person’s first name (string)?• Person’s last name (string)?• Member identification number (int)

• Number of books purchased (int)?• Amount of money spent (double)?The class memberType has member functions that perform operations on objects of memberType. For the mentioned pieces of data that an object of memberType has (first name, last name,?id, number of books purchased, money spent), there are member functions for setting, retrieving, and printing each of these values:

            (functions) for first name, last name, id, book purchased, and money spent. ?

            (functions) for first name, last name, id, book purchased, and money spent. ?

            function) prints first name, last name, Number of book purchased, and money spent. ?

            function. (it sets string variables to empty and integer and double variables to 0) ?Stage2: ?Define the functions bodies of the class memberType. Stage3: ?Use the following code as your driver program to test various operations of the class memberType such that it produces exact output as provided. ?

Output:

Additional requirements:

Use one source (.cpp) file for Question1

Comment your work. Also, put your name and lab number and question number on top of your(.cpp) file.

Part 2:

Stage1: Use question 1 and separate it into files for implementing the class (header file), defining the functions of the class (cpp file that maps to the header file), and testing the class by a driver program (cpp file with the main function).

Stage2: Add these extra functionalities to the memberType class and complete their functions.

Parameterized Constructor: It creates a new object and sets values for all member variables. ?

equal function: It compares the current object with another object, returns true if they are the same. ?
