- oop using c++ please give me full naswer thanks Design a class named Person and its two subclasses named Student and Employee. Design two more classes; Faculty and Staff and inherit them from Employee. The detail of classes is as under: A person has a name, email address, phone number and address. A student has a status (String). An employee has an office, salary, and date hired A faculty member has office hours and rank A staff member has a title. Create display method in each class. Also create getter, setter and default constructor in above task.True or False An interface can be used to define a set of methods that a class must implement.Code the StudentAccount class according to the class diagramMethods explanation:pay(double): doubleThis method is called when a student pays an amount towards outstanding fees. The balance isreduced by the amount received. The updated balance is returned by the method.addFees(double): doubleThis method is called to increase the balance by the amount received as a parameter. The updatedbalance is returned by the method.refund(): voidThis method is called when any monies owned to the student is paid out. This method can onlyrefund a student if the balance is negative. It displays the amount to be refunded and set thebalance to zero. (Use Math.abs(double) in your output message). If there is no refund, display anappropriate message.Test your StudentAccount class by creating objects and calling the methods addFees(), pay() andrefund(). Use toString() to display the object’s data after each method called
- The pillar that allows you to build a specialized version of a general class, but violates encapsulation principles isA SuperDie Class Write a class SuperDie that models a single die with an arbitrary number of sides, not just six. A die instantiated with the default constructor has six sides. The methods of this class should be: • roll a die and return its value, • return the number of sides on a die, and • change the number of sides on a die. Include a main(...) method that tests all the methods of your class.Defining Classes Write and document the definition for the Money class. The Money class represents an amount in U.S. dollars. Money Class e Fields cents : int dollars : int e Methods getValue() : double Money(int d, int c) setCents(int c) : void setDollars(int d) : void toString() : String • Each Money object has two int instance variables: dollars and cents. • The class has one constructor that takes two int parameters. The first int represents whole dollars, and the second int represents cents. • The class has one accessor method named getValue() which returns the amount as a double. (Just divide cents by 100.0 and add it to dollars. Return that amount.) • The class has two mutator methods-setDollars() and setCents()–that modify the corresponding instance variables. • The class has a toString() method that returns the amount as a String in the form: $ 2345.75. Use concatenation to produce the output. Do not worry about the decimal places.
- A(n) ____________ is one instance or variable of a class.Chapter 10 defined the class circleType to implement the basic properties of a circle. (Add the function print to this class to output the radius, area, and circumference of a circle.) Now every cylinder has a base and height, where the base is a circle. Design a class cylinderType that can capture the properties of a cylinder and perform the usual operations on the cylinder. Derive this class from the class circleType designed in Chapter 10. Some of the operations that can be performed on a cylinder are as follows: calculate and print the volume, calculate and print the surface area, set the height, set the radius of the base, and set the center of the base. Also, write a program to test various operations on a cylinder.The ability to create classes with more specific attributes and methods that share the properties and methods of existing classes is referred to as: Abstraction Polymorphism Typecasting Inheritance

The class should have: a constructor that accepts arguments for the two fields a method that returns the tract’s area(i.e. length * width) an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false. a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…1.
