- Create three classes Person, Professor and Student. Theclass Person should have data members name and age. Theclasses Professor and Student should inherit from theclass Person.The class Professor should have two integermembers: publications and cur_id. There will be two memberfunctions: getdata and putdata. The function getdata shouldget the input from the user: the name, age and publications ofthe professor. The function putdata should print the name,age, publications and the cur_id of the professor.The class Student should have two data members: marks,which is an array of size 6 and cur_id. It has two memberfunctions: getdata and putdata. The function getdata shouldget the input from the user: the name, age, and the marks ofthe student in 6 subjects. The function putdata should print 1,2,3,4,5,6,7,8,10,11 Students canbe able todevelop theProfessionalDataMaintenanceSystem. the name, age, sum of the marks and the cur_id of the student.For each object being created of the Professor…Write a C++ program(The Account Class) Design a class named Account that contains (keep the datafields private):a) An int data field named id for the account.b) A double data field named balance for the account.c) A double data field named annualInterestRate that stores the current interest rate.d) A no-arg constructor that creates a default account with id 0, balance 0, andannualInterestRate 0.e) The accessor and mutator functions for id, balance, and annualInterestRate.f) A function named getMonthlyInterestRate() that returns the monthly interest rate.g) A function named withdraw(amount) that withdraws a specified amount from the account.h) A function named deposit(amount) that deposits a specified amount to the account.Implement the class. Write a test program that creates an Account object with an account ID of1122, a balance of 20000, and an annual interest rate of 4.5%. Use the withdraw function towithdraw $2500, use the deposit function to deposit $3000, and print the balance,…C++ PROGRAM Create a class MyClass with an integer data member ‘secret’. Provide a constructor and display method in the class. Create another class, MyFriendClass and make it a friend of the class MyClass. Provide a function change() in the class MyFriendClass which accepts an object of class MyClass (by reference) and an integer. The change() function should assign the integer passed as an argument to the data member ‘secret’ of the object received as input. Sample Run : MyClass m(2) ; MyFriendClass mf ; mf.change(m,10) ; m.display() ; //Should print 10
- Computer Science Create a class STC with multiple functions prepaid, postpaid and roaming (add some features in prepaid and postpaid and roaming). Create object for the class and access the functions?C++ PROGRAM Create a class MyClass with a string data member ‘paragraph’. Provide a constructor, getParagraph() and display() method in the class. getParagraph() method must read a paragraph from a file. The display method should display that paragraph. Create another class, MyFriendClass and make it a friend of the class MyClass. Provide a function getWord(MyClass &obj1, int index) with return type string in the class MyFriendClass which accepts an object of class MyClass (by reference) and an integer. The getWord() function should return the word at location index passed as an argument to the data member ‘paragraph’ of the object received as input.i will upvotes unique answer plzz (Use language OOP in c++) Create a class Student with data members age and marks, both of type integer. Provide a parameterized constructor and a set member function to set the data members. The age should be a positive number between 15 and 40 while the marks should be between 0 and 100. Create a class InvalidRange as exception handler of the Student class. Add two private data members (a string and an integer) to theclass InvalidRange. Provide appropriate constructor and get methods for the data members. The string should store the name of the function throwing the exception while the integer should store the invalid value the user has supplied. The student class should throw an exception if any of its member functions attempts to assign an invalid value to the data members. In the main program, create objects of class student, assign valid/invalid values to the data members and catch the exceptions accordingly. Extend the program to have two…
- Exercise 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 accountCreate a class called Name that contains data members of type string called first name, middle name, last name, and salutation. Add a constructor that takes four parameters which are used to initialize the four data members and a member function called to-string that returns the person's full name in the form of “Salutation First name Middle name Last name”. Finally add set and get functions for all the data members. Add a destructor to the program displaying a suitable msg.In C++ class SaleItem{public:double getprice();void setprice(double);void setName(string);string getName();double TotalItemsPrice(int);private:double price;string name;}; In the class declaration above, what is the name of the class? Which lines have member access specifiers? Which lines contain data members of the class? Which lines contain accessor functions? Which lines contain mutator functions?
- Create an Employee class. Attributes(must be private): Employee has a name and basic_salary Methods:Employee(string, float); //ConstructorAllowances are computed as: float getHouseRent(); //House rent is 45% of the basic pay. float getMedicalAllowance(); //Medical Allowance is 5% of the basic pay. float getConveyanceAllowance(); //Conveyance allowance is 10% of the basic payfloat getGrossPay(); //Salary including rent and allowances{You can implement additional function/s if needed} Then Create an Organization class. Organization has 10 Employees (Hint: You will need an array of pointers to Employee class) Organization can calculate the total amount to be paid to all employees Organization can print the details(name & salary) of all employees Note: Use main,header and functions.cpp to write code.(C++) 17. True/False: a class may have more than one destructor. 18. True/False: assume a class has a default constructor implemented. Any time an object of this class is instantiated, a constructor is called. 19. Public members of an object may be accessed using the following operator: a) . b) > c) - d) None of these 20. A header file (.h file) of a class typically contains: a) The code to implement the class b) a program using the class c) The class declaration d) None of the aboveC- Create the sub class UsedBook that is derived from the super class Book and has the following instance variables, constructor, and functions: title ( String) isbn ( String) authors (String) publisher (String) edition ( int) published_year (int) price_new (double) // the price of the book if it is new age (int) // how old the book is in years Constructor that takes all of the above variables as input parameters. set/get functions calculate_price method // the price is calculated as price_new * (1- 0.10*age) print function that prints all information related to the old book. D- Create the Testing class that has the main method and does the following: aa- Use the constructor to create instance of NewBook class and name it as new. Call compute_price function. bb- Use the constructor to create instance of usedBook class and name it used. Call compute_price function. cc- Print the related information of new and used objects using print functions. Use this following code: class…
