Write a Circle class that has the following member variables: • radius : a double • pi : a double initialized with the value 3.14159 The class should have the following member functions: • Default Constructor. A default constructor that sets radius to 0.0. • Constructor. Accepts the radius of the circle as an argument. • setRadius. A mutator function for the radius variable. • getRadius. An accessor function for the radius variable. • getArea. Returns the area of the circle, which is calculated as area = pi * radius * radius • getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius

Circle Class (Easy) Write a Circle class that has the following member variables: radius : a double The class should have the following member functions: Default Constructor: default constructor that sets radius to 0.0. Constructor: accepts the radius of the circle as an argument. setRadius: an mutator function for the radius variable. getRadius: an accessor function for the radius variable. getArea: returns the area of the circle, which is calculated as area = pi * radius * radius getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius Step1: Create a declaration of the class. Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating Circle objects, and then reporting the circle’s area, and circumference. You should create at least two circle objects, one sets the radius to 0.0 and one accepts the radius as an…
ngineering Computer ScienceQ&A Libraryin c++ Create a class time24, each object is a value represented the time of day in the form hours, minutes and seconds. Provide a constructor that enables an object of this class to be initialized when it is instantiated. The constructor should contain default values in case no initializes are provided. Provide Public member functions for each of the following operations: set the time, print the time, increment the time by one second, compare two times for equality, increment the time by one hour, determine if one time is “less than” (comes before) another time, and final print the time in format 12 hours. Include any additional operations that you think would be useful for your class. Design, implement, and test your class. in c++ Create a class time24, each object is a value represented the time of day in the form hours, minutes and seconds.

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…
C++ Friend function concepts Do not use operator overloading Create a class User with private member variables "id". In the class define a function increment_user_id() which will increment the id and return it as well. Create another method "void show_Id()" to show the id for a particular object. Create a constructor of User class where increment the Id by calling the increment_user_id() method for every new object . Finally create two objects of the class and print their corresponding id's on console.
C++ True/False: a member function in a class can access all of its class's member variables, but not if the variables are private.

Problem: Employee and ProductionWorker Classes Write a python class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: • Shift number (an integer, such as 1, 2, or 3)• Hourly pay rateThe workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for this class. Once you have written the class, write a program that creates an object of the ProductionWorker class, and prompts the user to enter data for each of the object’s data attributes. Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen Note: The program should be written in python. Sample Input/Output: Enter the name: Ahmed Al-AliEnter the ID number: 12345Enter the department:…
C++ Write a Cuboid class that has the following member variables: • length (l) • width (w) • height (h) The class should have the following member functions: • Default Constructor: A default constructor that sets length, width, and height all to 1.0. • Another Constructor: Accepts the length, width, and height of the cuboid as arguments. • getV: Returns the volume of the cuboid.• getS: Returns the surface area of the cuboid. • A Destructor: Print e.g. Cuboid(1.0 x 2.3 x 5.6) is deleted.. The number is the length, width and height of the cuboid.
C++ oop using classes only You are going to make an employee management system. In this lab, you have to create anEmployee class only. Employee class fields are: Employee Name, Employee ID, andEmployee Gender. The member functions include the getters and setters for all the membervariables and display () function to display the data. In the main function, first create twoEmployee objects and allow the user to enter data in these objects. Secondly, display thedata from these objects.
Animal Lab The objective of this assignment is to give you some practice using inheritance, virtual functions, and polymorphism. Instructions: Create a base class called Animal. All animals have a name (i.e. “Fido,” “Thumper,” “Princess,” “Nemo,” etc.) and an age. Provide a default constructor that initializes the age to zero and outputs the message “Invoking the default Animal constructor” and another constructor that allows the name and age to be set by the client. This other constructor should also output the message “Invoking the 2-argument Animal constructor.” Also construct a destructor for this class that outputs the message “Invoking the default Animal destructor.” Your Animal class should have a function called Move that cannot be implemented. That is, it should be declared as a purely virtual function. Your class should also have Get and Set methods to allow the name and age to be accessed. From the Animal class, derive Dog, Rabbit, Fish, and Snake classes. The derived…
C++ Programming Assignment 6 Dynamic Pets The objective of this lab is to demonstrate dynamic allocation and deallocation of memory. Instructions: Write a class called Pet that contains an animal’s name, type, and weight. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new pet”. The destructor should print out the following message: “In the Pet destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of pets in his or her household. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Pet objects. Construct a loop in main() that executes once for each of the number of pets that the user indicated. Within this loop, ask the user to enter the name and type of pet. Using a random number generator, generate a weight between 1-100 pounds. Seed this random number generator with 100.…
