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:
Fill the gap: The________declares that a derived class is allowed to override a method.
Step by step
Solved in 2 steps
- Fill-in-the-Blank In order to use dynamic binding, a member function of a class needs to be declared as a(n) _________ function.Fill-in-the-Blank A constructor that takes a single parameter of a type different from the class type is a __________ constructor.Fill in the blank: A(n)________specifies how a class member can be accessed by code outside the class.
- Fill-in-the-Blank When both a base class and a derived class have constructors, the base class’s constructor is called __________ (first/last).Fill-in-the-Blank A member function of a class that is not implemented is called a(n) _________ function.TRUE or FALSE - Constructor of base class is derived from the derived classes. Select one: a. TRUE b.FALSE
- False True Adding a derived class to a base class requires substantial changes to the base class1. 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, then use the object’s accessor methods to retrieve it and display it on the screen. 2. ShiftSupervisor Class In a…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.
- 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, then use the object's accessor methods to retrieve it and display it on the screen.#include<iostream> using namespace std; class Vehicle // superclass{private: int x = 7; // only class vehicle objects can accessprotected: int y = 3; // only class vehicle and kid objects can access public: int get_x() // Accessed by all { return x; }}; class Car : public Vehicle // subclass or child of class vehicle AND Parent of Corvette class{private: int z = 4; // only a class car object cna accessprotected: int w = 2; int get_y() { return y; } int get_z() { return z; }public: int get_z3() { return z; }}; class Corvette : public Car // subclass of car class{private: int d = 8;public: int get_d() { return d; } int get_z2() { return get_z(); }}; class Mustang : public Car // Hierarchical Mustang and Corvette{private: int u = 99;public: int get_u() { return u; }}; int main(){ Vehicle vehicle;…8. Circle ClassWrite a Circle class that has the following member variables:• radius: a double• pi: a double initialized with the value 3.14159The 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• getDiameter. Returns the diameter of the circle, which is calculated as diameter = radius * 2• getCircumference. Returns the circumference of the circle, which is calculated as circumference = 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.…
