Write a C++ program that does the following:
Create a class called Student
This class has the following private attributes:
• Name
• Age
• GPA
This class has the following methods:
• Default constructor
• Non-default constructor that will initialize all the above attributes
• Set/Get method for each of the above attributes
• DisplayStudent that will print the information for the student all three values on the same line with proper spacing
• Destructor method that will print a message that the object has been deleted
Your main function should do the following
o Ask the user how many students to create
• Create an array of objects of type Student (studentArr)
o Call a function called acceptStudentinfo.This function will accept the array along with any needed parameters to allow the user to enter the
values for the different students
o Call a function called displayStudentlnfo. This function will accept the array along with any needed parameters to display the content of all
students

Write a class named Employee that has the following member variables:
name. A string that holds the employee’s name.
idNumber. An int variable that holds the employee’s ID number.
department. A string that holds the name of the department where the employee works.
position. A string that holds the employee’s job title.
The class should have the following constructors:
A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position.
A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string ("").
A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable.

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.arrow_forward
