- 2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results. Statements and Expressions Value Returned Comment (blank if no value) StepTracker tr StepTracker(10000); Days with at least 10,000 steps are considered active. Assume that the parameter is positive. new tr.activeDays () ; No…C++ In this problem, you will use the Bubble class to make images of colorful bubbles. You will use your knowledge of classes and objects to make an instance of the Bubble class (aka instantiate a Bubble), set its member variables, and use its member functions to draw a Bubble into an image. Every Bubble object has the following member variables: X coordinate Y coordinate Size (i.e. its radius) Color Complete main.cc Your task is to complete main.cc to build and draw Bubble objects based on user input. main.cc already does the work to draw the Bubble as an image saved in bubble.bmp. You should follow these steps: First, you will need to create a Bubble object from the Bubble class. Next, you must prompt the user to provide the following: an int for the X coordinate, an int for the Y coordinate, an int for the Bubble's size, and a std::string for the Bubble's color. Next, you must use the user's input to set the new Bubble object's x and y coordinates, the size, and the color using…C++ Write a class named Car with member variables: yearModel, Make, Speed as private.Use a Constructor that accepts year model and make as arguments. It should also assign 0 to thespeed use accelerate and brake functions that add and subtract 5 from speed each time it is called.Demonstrate the class in a program that creates a Car object, and then calls the acceleratefunction 5 times. After each call to the accelerate function, get the current speed of the car anddisplay it. Then, call the brake function five times. After each call to the brake function, get thecurrent speed of the car and display it

(in the attachments) The CashRegister class should simulate the sale ofa retail item. It should have a constructor that accepts a RetailItem object as an argument.The constructor should also accept an integer that represents the quantity of items beingpurchased. In addition, the class should have the following methods:• The getSubtotal method should return the subtotal of the sale, which is the quantitymultiplied by the price. This method must get the price from the RetailItem objectthat was passed as an argument to the constructor.• The getTax method should return the amount of sales tax on the purchase. The salestax rate is 6 percent of a retail sale.• The getTotal method should return the total of the sale, which is the subtotal plus thesales tax.Demonstrate the class in a program that asks the user for the quantity of items being purchased,and…Use Python Programming Language Write code that defines a class named Animal: Add an attribute for the animal name. Add an eat() method for Animal that prints ``Munch munch.'' A make_noise() method for Animal that prints ``Grrr says [animal name].'' Add a constructor for the Animal class that prints ``An animal has been born.'' A class named Cat: Make Animal the parent. A make_noise() method for Cat that prints ``Meow says [animal name].'' A constructor for Cat that prints ``A cat has been born.'' Modify the constructor so it calls the parent constructor as well. A class named Dog: Make Animal the parent. A make_noise() method for Dog that prints ``Bark says [animal name].'' A constructor for Dog that prints ``A dog has been born.'' Modify the constructor so it calls the parent constructor as well. Create a test program that will: Code that creates a cat, two dogs, and an animal. Sets the name for each animal. Code that calls eat() and make_noise() for each animal. (Don't…
- :Define and implement class Employee. This class should contain the following fields: first name, last name, employee id, hourly pay. This class should contain getters and setters for all its attributes. This class also needs at least one constructor. Implement method computePay() in this class. This method should accept an integer number of hours the employee worked as an input argument and return a floating point value indicating the pay the employee earned. If the number of hours is invalid (e.g. a negative number) this method should throw NumberFormatException. If the number of hours is over 40 then this method should throw a custom exception named TooManyHoursWorkedException. Remember that you will have to define your own exception class for this. Save this class and its definition into a file named Employee.java. Define and implement class EmployeeTest.This class should implement main() method. In the body of the main() method you should create an instance of Employee with the…In C++ Define a class named Complex that will represent complex numbers. Acomplex number is a number of the forma+b*i,where, for our purposes, a and b are integers and i represents sqrt(-1).In your class, include a constructor that takes two parameters andinitializes a and b to the first and second parameter respectively, and includea constructor that takes one parameter and initializes a to the value of theparameter and b to 0. Also include a default constructor that initializes both aand b to 0. Overload all of the followind operators so that they correctly applyto the class Complex: ==, +, -, *, >>, and <<.Using your Complex class, write a program that would let the user input twocomplex numbers, and then print out their sum, difference, product, and whetherthey are equal to one another.How many default constructors can a class have? a. A class cannot have a default constructor. b. only one c. as many as it needs d. one or more, but fewer than three
- Write a Rectangle class that has the following fields: Length (L): a double - Width (W): a double The class should have the following functions: Constructor: accepts the length (L) and the width (W) of a rectangle as arguments. Constructor: does not take any parameters and initializes the length(L) and width(W) to zero. - A function called getArea which returns the area of the rectangle. A function called getPerimeter which returns the perimeter of the rectangle. {note: The area of a rectangle =L*W, and its perimeter = 2*(L+W) } Then, write a program to ask the user to enter the length and width of a rectangle, and then use the above class to calculate and print the area and perimeter of the rectangle.Please help with the following: C# .NET change the main class so that the user is the one that as to put the name Write a driver class (app) that prompts for the person’s data input, instantiates an object of class HeartRates and displays the patient’s information from that object by calling the DisplayPatientRecord, method.
