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:
2. Insert a function that prints a greeting, and execute it on the p1 object

- c++ Implement a Class Book. Book shall have the following members: A member variable title of type std :: string.A member variable pages of the type unsigned int.A member variable current_page of type unsigned int.A parameterized constructor that takes title and pages as input parameters.A change_page function to scroll to a given page.A next_page function to scroll to the next page.A prev_page function to scroll to the previous page.A superimposed outflow operator (<<) that prints current_page.It is not allowed to scroll outside the pages of the book (0 <current_page <pages). The members must be encapsulated in accordance with the usual convention. Create goat and set functions as needed. Input follows the format: title pages start_page Output should have the following format:current_page repeated three times after calling change_page, next_page, prev_page in sequence, see comments below.

- Reuse your Car class . In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. Now, build a toString function that prints out the make, model, and odometer reading for a vehicle object. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */ public int getOdometer() { return odometer; } public void…Implement the Rectangle class as discussed this week. Use the class declaration below. Your job is to implement the functions. Implement the missing functions yourself. class Rectangle{ private: double width; double length; char *name; void initName(char *); public://constructorsRectangle();Rectangle(double, double, char*);//destructor ~Rectangle(); void setWidth(double); void setLength(double); void setWidth(char *); void setLength(char *); void setName(char *); double getWidth() const; double getLength() const; void printName() const { cout << name; }}; A few notes on the functions: initName(char *): this is a private member function. It should be the only function which dynamically allocates a char array to hold the name. setName(char *): this is a public member function which changes the name of the rectangle to a new name. It does not dynamically allocate memory, it only changes name. Demonstrate your class works…Given the provided class, please make the following modifications. class Employee: def __init__(self, name, number): self.name = name self.number = number class ProductionWorker(Employee): def __init__(self, name, number, shift_number, employee_number): Employee.__init__(self, name, number) self.shift_number = shift_number self.employee_number = employee_number # Create an instance of the ProductionWorker class and test itemployee1 = ProductionWorker("John Doe", 1234, 2, 5678)print(employee1.name)print(employee1.number)print(employee1.shift_number)print(employee1.employee_number) Write a class 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.
