OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Demonstrate the classes by writing a program that uses a production worker object . note: please submit 3 files employee.h productionWorker.h cpp filePLZ help wiith the following: IN JAVA If an inner class contains non static members, then the class name must be modified by the keyword: Final Static Void Protectedc++ please The Critter class is a base class with some basic functionality for running simulations of different kinds of critters. Critters can move, act, and remember their history. A typical simulation contains a number of critters of different types. In each step of the simulation, the act member function will be called on each critter. Define a class Sloth derived from Critter that simulates a sloth. Sloths alternate between eating and sleeping. Add the word "eat" or "sleep" to the history each time the act function is called. The implementation of the Critter class is not shown.

- writte in c++ 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 * radiusProgram SpecificationUsing python, design a class named PersonData with the following member variables: lastName firstName address city state zip phone Write the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData , which is derived from the PersonData class. The CustomerData class should have the following member variables: customerNumber mailingList The customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool . It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mail-ing list. Write appropriate accessor and mutator functions for these member variables. Next write a program which demonstrates an object of the CustomerData class in a program. Your program MUST use exception handling. You can choose how to implement the exception handling. Start your program with a welcome message Make sure…Programming Language = Python 1. Employee and ProductionWorker Classes Write an Employee class that keeps data attributes for the following pieces of information: • Employee name • Employee number Next, write a 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 rate The 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 each class. Once you have written the classes, 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 and then use the object’s accessor methods to retrieve it and display it on the…
- Members of a base class may be accessible via the base-class definition, derived-class definitions, and friends of the base class and its derived classes..........Write a C++ program that includes a class called PC. The private members of the class include the following identifiers: •itemName (string datatype) The protected member • cpu_gen (integer datatype) • Item_prise(double datatype) The public modifier includes: • Default constructor function that creates default values for private identifiers. • constructor function to input private data for each item. • friend function that increases each item_prise by 1.5. • Function print private_data for each object. Then create two objects PC1, PC2, and one pointer object PC2P point to PC2 and then print the information of PC1, and print the information of PC2 by its pointer. Finally, create a new class called laptop (drive class ) inherent from class PC (base class) includes the following private member : Lap_size (double datatype ) Public member : Default constructor function that creates default values for private identifiers. • Constructor function to input private data for each item. Then create…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.
- In C++ Q1.) Write a Review class that has: • These private data members: • string user: ID of the user • string item: ID of the item • double paid: the price of the item that the user buys • double rating: the rating that the user gives to the item • string review: the review content that the user gives to the item • These public member functions: • A default constructor to set all instance variables to a default value • A parameterized constructor (i.e., a constructor with arguments) to set all instance variables • A method for getting/setting the instance variables. • A method for printing the Review's information.C++ question define a class “InternationalStudent” that is a derived class of the base class “Student” given in the code below. class “InternationalStudent” should have an additional data field “nation” of type string ; one additional member function “IsFunded” that takes no arguments and returns a value of type bool ; and “suitable constructors”. Complete this code with the requirements above : class Student{public:Student( );void printInfo( ) const;protected:int id;string name;};C++ Define a Class Time with the following data members: hour, minute, and the following member functions: 1. Set_ data: that Stores parameters values into data members. 2. Update_time: that update the existing time by certain value (Add hours with hours and minutes with minutes). 3. Sum_time: that find the sum of given two times. 4. Ret_hm: that returns the hour and the minute of the time. Let your main function declare two objects, and print the values of the hour (h) and the minute (m) for the fastest time.
