Write a class named Car that has the following member variables: Year: An int that holds the cars year model. Model: A string that holds the brand of the car. Speed: An int that holds the cars current speed. Color: A string that holds the color of the car. In addition, the class should have the following constructor and other member functions: Constructor: The constructor should accept the cars year, model ,speed and color as arguments. Accessor: Appropriate accessor functions to get the values stored in an object. Accelerate: The accelerate function should add 10 to the speed member variable If it’s value smaller than 50. Brake: The brake function should subtract 15 from the speed member variable If it’s value larger than 130. Count: The count function classifies the cars according to their model and their color. Afterward display the count of cars model= BMW and color=Red. Establish the class in a program that creates ten Car objects, and then calls the accelerate function ten…

Parking Ticket SimulatorFor this assignment you will design a set of classes that work together to simulate apolice officer issuing a parking ticket. The classes you should design are:• The Parkedcar Class: This class should simulate a parked car. The class's respon-sibilities are:To know the car's make, model, color, license number, and the number of min-utes that the car has been parkedThe BarkingMeter Class: This class should simulate a parking meter. The class'sonly responsibility is:- To know the number of minutes of parking time that has been purchased• The ParkingTicket Class: This class should simulate a parking ticket. The class'sresponsibilities areTo report the make, model, color, and license number of the illegally parked carTo report the amount of the fine, which is $2S for the first hour or part of anhour that the car is illegally parked, plus $10 for every additional hour or part ofan hour that the car is illegally parkedTo report the name and badge number of the police…
T/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.

Employee Class (Medium) Write a class named Employee that has the following member variables: name. A string that holds the employee’s name. idNumber. An int variable that holds the employee’s ID number. department. A string that holds the name of the department where the employee works. position. A string that holds the employee’s job title. The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string (""). A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable. Write appropriate mutator functions that…
Freezing and Boiling PointsThe following table lists the freezing and boiling points of several substances.Substance Freezing Point || Boiling PointEthyl Alcohol -173 || 172Oxygen -362 || -306Water 32 || 212Design a class that stores a temperature in a temperature field and has the appropriate accessor and mutator method for the field. In addition to appropriate constructors, the class should have the following methods:• isEthylFreezing. This method should return the boolean value true if the tempera-ture stored in the temperature field is at or below the freezing point of ethyl alcohol. Otherwise, the method should return false.• isEthylBoiling. This method should return the boolean value true if the tempera-ture stored in the temperature field is at or above the boiling point of ethyl alcohol. Otherwise, the method should return false.• isOxygenFreezing. This method should return the boolean value true if the tem-perature stored in the temperature field is at or below the freezing…
Write a class named Car that has the following private member variables: yearModel: An int that holds the car's year model make: A string that holds the make of the car speed: An int that holds the car's current speed In addition, the class should have the following public member functions: Constructor: Accepts two arguments. The first argument is the car's year model, and the second argument is the car's make. These values should be assigned to the yearModel and make member variables. This constructor should assign 0 to the speed field. Default Constructor: Sets the yearModel member variable to 2022, sets the make member variable to an empty string (""), and sets the speed member variable to 0. setYearModel: Accepts an int argument that is assigned to the yearModel member variable. The function returns no value. setMake: Accepts a string argument that is assigned to the make member variable. The function returns no value. setSpeed: Accepts an int argument that is assigned to the speed…
Dynamic Games Instructions: Write a class called Game that contains a video game’s name, genre, and difficultyLevel. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new game”. The destructor should print out the following message: “In the Game destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of games he or she has played in the past year. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Game objects. Construct a loop in main() that executes once for each of the number of games that the user indicated. Within this loop, ask the user to enter the name and genre of each game. Using a random number generator, generate a difficultyLevel between 1-10 (inclusive). Seed this random number generator with 100. Next, dynamically create a Game object (remember that this…
Circle ClassWrite a Circle class that has the following fields:• radius: a double• PI: a final double initialized with the value 3.14159The class should have the following methods:• Constructor. Accepts the radius of the circle as an argument.• Constructor. A no-arg constructor that sets the radius field to 0.0.• setRadius. A mutator method for the radius field.• getRadius. An accessor method for the radius field.• area. Returns the area of the circle, which is calculated asarea = PI * radius * radius• diameter. Returns the diameter of the circle, which is calculated asdiameter = radius * 2• circumference. Returns the circumference of the circle, which is calculated ascircumference = 2 * PI * radiusWrite a program that demonstrates the Circle class by asking the user for the circle’s radius, creating a Circle object, and then reporting the circle’s area, diameter, and circumference.
