Define a class called PartFilledArrayWMax that is a derived class of the class PartFilledArray. The class PartFilledArrayWMax has one additional member variable named maxValue that holds the maximum value stored in the array. Define a member accessor function named getMax that returns the maximum value stored in the array. Redefine the member function addValue and define two constructors, one of which has an int argument for the maximum number of entries in the array. Also define a copy constructor, an overloaded assignment operator, and a destructor. (A real class would have more member functions, but these will do for an exercise.)

- Create a SavingsAccount class. Use a static data member annualInterestRate to store the annual interest rate for each of the savers. Each member of the class contains a private data member savingsBalance indicating the amount the saver currently has on deposit. Provide member function calculateMonthlyInterest that calculates the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12; this interest should be added to savingsBalance. Provide a static member function modifyInterestRate that sets the static annualInterestRate to a new value. Write a driver program to test class SavingsAccount. Instantiate two different objects of class SavingsAccount, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set the annualInterestRate to 3 percent. Then calculate the monthly interest and print the new balances for each of the savers. Then set the annualInterestRate to 4 percent, calculate the next month’s interest and print…arrow_forward1- A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b). The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.arrow_forwardDefine two classes A and B each having one String private data member. Write zero argument and parameterized constructors to initialize the data member and member functions to get, set and display the data member for these classes. In the demo class, write a concat() function which takes the 2 arguments as class A and class B objects and concatenates the data ac members of these two objects. Write main method that creates instances of the classes A and B, assigns values to each and concatenates the value of data member of these objects using the concat() function. Display the objects before and after concatenation.arrow_forward
- Create a class Calculator having two integer data members and one string member i.e. operator. Class contains only one customized constructor which take two arguments, set the default values 1 if no argument is passed through the constructor. Class Calculator also contains a member function Calculate() that takes an operator (string) as an argument and compute it. Only four operators are allowed i.e. +, -, *, /arrow_forwardWrite a class Box having three private data members (width, depth, height) The class has three constructors which are having no parameter – for setting values to zero or null. having three parameters for assigning values to height, width, depth respectively. Overload the above constructor and use this keyword to set the values of width, height & depth. Provide getters/setters for data members. Write a function calculateVolume() which calculates the volume of the box. Write test Application that demonstrates the Box class by calling all the three constructors and method, creating a Create Box object, and then displaying the Box’swidth , height, length and volume .arrow_forwardWrite base class with the name Shape . The Shape class have Private Variable: area, a double used to hold the shape's area. Public Member Functions: getArea the Accessor. This function should return the value in the member variable area. Parameterized constructor—Initializes area member. Defualt constructor— Empty body calcArea. This function should be a incomplete function.Next, define a class named Triangle . It should be child of Shape class. It should have the following members:Protected Member Variables: base, a integer used to hold the base of triangle.Height, a integer used to hold the height of the triangle. Public Member Functions: constructor—Initializes values for base, height. The overridden calcArea function in Circle described below.calcArea—calculates the area of the Triangle (1/2* base * height) and stores the result in the inherited member area.After you have created these classes, create a driver program that defines a Triangle object.

- Design a class bookType that defines a book as a class. a. Each object of the class bookType will hold the following information about a book: title number of authors up to four authors publisher year published ISBN 13 (with dashes) price number of copies in stock (may be 0) b. Include the member functions to perform the various operations on objects of type bookType: Include individual get and set functions for all member variables. c. Add a member function to update the number of copies in stock. d. Add the appropriate constructors and a destructor (if one is needed). Ensure a default constructor is coded and the constructor initializes all data members. Remember, an array of classes uses a default constructor only. e. ALL member variables must be private and accessed through member functions. The main client program CANNOT access the variables directly. f. Ensure the class declaration and class implementation files are in separate header and code (.cpp) files. This assignment will…arrow_forwardAssume the existence of a Phone class.Define a derived class named CameraPhone that contains two member variables: An int named imageSize that contains the umber of megabytes that a picture uses on the phone. An int named memorySize that contains the number of megabytes in the camera's memory. Write the following member functions in the CameraPhone class: A constructor that accepts two int arguments. The first argument should be assigned to the imageSize member, and the second argument should be assigned to the memorySize argument. A member function named numPictures that returns (as an int) the number of pictures the camera's memory can hold.arrow_forwardIn the Member class, complete the function definition for SetNumPoints() that takes in the integer parameter newNumPoints.
