- People in School Objective: At the end of the activity, the students should be able to: Create a program that exhibits inheritance. Procedure: Write a simple information system that will store and display the complete information of a student, faculty, or employee. Create four (4) no-modifier classes named Person, Student, Faculty, and Employee. Create a public class named CollegeList. This class shall contain the main method. Refer to the UML Class Diagram for the names of the variables and methods. The (-) symbol represents private variables, while (+) represents public method. This should be the sequence of the program upon execution: Prompt the user to select among Employee, Faculty, or Student, by pressing E, F, or S. Ask the user to type the name and contact For Employee, ask the user to type the employee's monthly salary and the department where he/she belongs to (Ex. Registrar). Then, display name, contact number, salary, and For Faculty, ask the user to press Y if…Part 1: Create a class DateType that has the following member variables: day (int), month(int), and year(int). - Your class should have the following member functions: o Parametrized default constructor. o Destructor o A get function for each member variables - Your class should also have the following friend functions: o Overload insertion operator to print date to screen o Overload extraction operator to read date from user Part 2: Create a class PersonType that has the following member variables: id(int), name(string), birthdate (DateType), and gender (char). - Your class should have the following member functions: o Parametrized default constructor. o Destructor. o A get function for each member variables o Overload == operator to check if two persons have equal ids or not. - Your class should also have the following friend functions: o Overload insertion operator to print person info to screen o Overload extraction operator to read person info from userProgramming Assignment #5 Educational Objectives: After completing this assignment the student should have the following knowledge, ability, and skills: Define a class hierarchy using inheritance Define virtual member functions in a class hierarchy Implement a class hierarchy using inheritance Implement virtual member functions in a class hierarchy Use initialization lists to call parent class constructors for derived class constructors Operational Objectives: Create (define and implement) a base class Shape classes that will inherit this class called Box, Rectangle, Circle, and Triangle Description: Programming Specifications: You will have a base class of Shape which will have an area and perimeter of type double. You must also create acceptable Gets and Sets for the private data items. All of the other classes will inherit this class. You will have a class Square which will have just one length of type double. You should create acceptable Gets and Sets for the one…

- When a class declares an entire class as its friend, the friendship status is reciprocal. That is, each class's member functions have access to the other's private members. True FalseExercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the accountPart I: Class Creation Create a composition between the classes Job and Salary. Class Salary a. data member: 1. money b. constructors: 1. default constructor 2. user defined constructor with a parameter to set money c. standard accessor and mutator functions Class Job a. data members: title (name of the job) salary (object of type Salary) b. constructors: 1. default constructor 2. user defined constructor to set title and salary 3. implement constructor delegation c. standard accessor and mutator function for title
