Chapter 21, Problem 21.16E
(Complex Class) Write a
- Create a user-defined class Complex that contains the private integer data members real and imaginary and declares stream insertion and stream extraction overloaded operator functions as friends of the class.
- Define the stream insertion and stream extraction operator functions. The stream extraction operator function should determine whether the data entered is valid, and, if not, it should set failbit to indicate improper input. The input should be of the form
- The values can be negative or positive, and it’s possible that one of the two values is not provided, in which case the appropriate data member should be set to 0. The stream insertion operator should not be able to display the point if an input error occurred. For negative imaginary values, a minus sign should be printed rather than a plus sign.
- Write a main function that tests input and output of user-defined class complex, using the overloaded stream extraction and stream insertion operators.

- Create a struct called Complex for performing arithmetic with complex numbers. Write a driver program to test your struct. Complex numbers have the form: realPart + imaginaryPart * iwhere i is the square root of -1Use double variables to represent data of the struct. Provide a function that enables an object of this struct to be initialized when it is declared. The function should contain default values in case no initializers are provided. Also provide functions for each of the following:a) Addition of two Complex numbers: The real parts are added together and the imaginary parts are added together.b) Subtraction of two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand and the imaginary part of the right operand is subtracted from the imaginary part of the left operand.c) Printing Complex numbers in the form (a, b) where a is the real part and b is the imaginary partSubmit one file which contains all code above: the structure…
(Tic-Tac-Toe) Write a program that allows two players to play the tic-tac-toe game. Your program must contain the class ticTacToe to implement a ticTacToe object. Include a 3-by-3 two-dimensional array, as a private member variable, to create the board. If needed, include additional member variables. Some of the operations on a ticTacToe object are printing the current board, getting a move, checking if a move is valid, and determining the winner after each move. Add additional operations as needed.
(c++)
Balance
Number of deposits this month
Number of withdrawals
Annual Interest Rate
Monthly service charges
The class should have the following member function:
Constructors
Accepts arguments for the balance and annual interest rate.
deposit
a virtual function that accepts an argument for the amount of the deposit. The function should add the argument to the account balance.
It should also increment the variable holding the number of deposits.
withdraw
a virtual function that accepts an argument for the amount of the withdrawal. The function should subtract the argument from the account balance. It should also increment the variable holding the number of withdrawals.
calcInt
a virtual function that updates the balance by calculating the monthly interest earned by the account, and adding this interest to the balance. This is performed by the account, and adding this interest to the balance. This is performed…

- C++ OOP Create a Student class, where attributes associated with each student are name, registrationnumber, father name, degree and department. All attributes should not be accessed directly.One can view the details of all students. Note student attributes can not be changed by anymeans after initialization. (Hint use constant objects).In student class maintaining student count means your program could be able totell the count of student objects created. (User static counter variable)arrow_forwardTopical Information Use C++. This lab will help you practice with dynamic memory (NOT mixed with classes). Program Information One statistic of interest to many researchers is the median of a set of data. The median is the value in the middle. (This is NOT the average, mind you.) Being in the middle, of course implies that the data are in order (sorted). If there are an odd number of data items, the middle is simple to find. If there are an even number of data items, you are supposed to take the average of the two middle values. You'll need to find the median of a set of data from a file. You don't know how many data are in the file, of course. You'll have to count the data, then read them in to sort, then find the median, and finally print it (the median) out. Do NOT use any more memory than is necessary!!arrow_forwardplease use c# (Rectangle Class) Create class Rectangle. The class has attributes length and width, each of which defaults to 1. It has read-only properties that calculate the Perimeter and the Area of the rectangle. It has properties for both length and width. The set accessors should verify that length and width are each floating-point numbers greater than 0.0 and less than 20.0. Write an app to test class Rectangle. explain each step wellarrow_forward

Suppose you are working as RA (research assistant) with a Professor who isworking on a project and evaluating complex mathematical equations. Your duty is to assist him, so in thisregard he has assigned a task to you. Your task is to write a oop c++ program to create a class named equation which will have the data members a, b and c which are the coefficients of the quadratic equation. The class will have two more data members namely proot and nroot which stand for the positive root and negative root of the equation. Suppose that variables a, b and c are integers. Where proot and nroot are floats. Input Function to get values of a, b and c Then design a friend function which will determine the proot and nroot of the equation. Create another friend function which will display the values of proot and nroot.arrow_forwardPlease fill in the blanks for the following statements: The class function with no return type that is used to initialize data members is called the __________________________.arrow_forward
- (TicTacToe Class) Create a class TicTacToe that will enable you to write a complete programto play the game of tic-tac-toe. The class contains as private data a 3-by-3 two-dimensional arrayof integers. The constructor should initialize the empty board to all zeros. Allow two human players.Wherever the first player moves, place a 1 in the specified square. Place a 2 wherever the second player moves. Each move must be to an empty square. After each move, determine whether the gamehas been won or is a draw. If you feel ambitious, modify your program so that the computer makesthe moves for one of the players. Also, allow the player to specify whether he or she wants to go firstor second. If you feel exceptionally ambitious, develop a program that will play three-dimensionaltic-tac-toe on a 4-by-4-by-4 board.
