Concept explainers
Define a class for a type called CounterType. An object of this type is used to count things, so it records a count that is a nonnegative whole number. Include a default constructor that sets the counter to zero and a constructor with one argument that sets the counter to the value specified by its argument. Include member functions to increase the count by 1 and to decrease the count by 1. Be sure that no member function allows the value of the counter to become negative. Also, include a member function that returns the current count value and one that outputs the count to a stream. The member function for doing output will have one formal parameter of type ostream for the output stream that receives the output. Embed your class definition in a test

- Write a full class definition for a class named Counter , and containing the following members: A data member counter of type int . A constructor that takes one int argument and assigns its value to counter . A function called increment that accepts no parameters and returns no value. increment adds one to the counter data member. A function called decrement that accepts no parameters and returns no value. decrement subtracts one to the counter data member. A function called getValue that accepts no parameters. It returns the value of the instance variable counter .arrow_forwardWrite 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.arrow_forwardC# languageWrite a program to create a class employee, it consist of ID, name, department and address. All employees belongs to “Computer Science” department and it can never be changed by any means. Employee ID is initialized only once when Employee object is created, any further attempt to change ID should be failed. Class must have a 3 parameterized constructor to set values and two methods: print(): to display all the data of a particular employee totalObjects(): to count and print total number of objects that has been created In Main(), create atleast two objects of employee class, display their records by calling print() function and also print the total number of objects that has been created. [this question is continued on next page] Sample Main Method: static void Main(string[] args) { Employee obj1 = new Employee(1, "Zubair", "Karachi"); obj1.print(); Employee obj2 = new Employee(2, "Nabeel", "Islamabad"); obj2.print();…arrow_forward
- 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.arrow_forwardWhen a class can be derived from another class and use its methods, this is called Polymorphism. A.

- C++ Language Please Write a program that implements four classes: NPC, Flying, Walking, and Generic for a fantasy roleplaying game. Each class should have the following attributes and methods: NPC -a parent class that defines methods and an attribute common to all non-player characters (npc) in the game. a private string variable named name, for storing the name of the npc. a default constructor for setting name to "placeholder". an overloaded constructor that sets name to a string argument passed to it. setName - a mutator for updating the name attribute getName - an accessor for returning the npc name printStats - a pure virtual function that will be overridden by each NPC subclass. Flying - a subclass of NPC that defines a flying npc in the game a private int variable named flightSpeed for tracking the speed of the npc. a default constructor for setting flightSpeed to 0 and name to "Flying" using setName. setFlightSpeed - a mutator that accepts an integer as it's only argument…arrow_forwardThere are two types of data members in a class: static and non-static. Provide an example of when it might be useful to have a static data member in the actual world.arrow_forward2019 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.

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…arrow_forwardParent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…arrow_forward
