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:
Step by step

- Can we use a default constructor of a class even if an explicit constructor is defined?constructor Bill_Details(String) is already defined in class Bill_Details plz how can i fix this problem . in this program i need to get a constructer from each classWhat is the order of Destructors call when the object of derived class child is declared, provided class child is derived from class parent? Select one: a.Destructor of parent only b.Destructor of child followed by parent c.Destructor of parent followed by child d.Destructor of child only
- 1- Implement the class “cylinder” with member variables radius and height, whichare private of type double. Define the global constant PI=3.1415 and use it incalculating the volume of the cylinder (PI*radius*radius*height).Implement in the class cylinder the following functions:a- A default constructor with default values of one.b- One constructor with two arguments. This constructor should check that thevariable is positive and does not exceed 20, otherwise the variable will beassigned its default value of one.c- A reader for each variable.d- A writer for each variable.e- A reader and a writer for diameter.f- A member function “volume” which calculates the volume of a cylinder.g- A member function “print” which prints the radius, diameter, and height of acylinder.h- A member function display_name() which displays “cylinder”.2- Write a program which declares an array of n cylinders (use n=5). Initialize thearray values by writing a loop which asks the user to input the radius and…Please solve in C++ You are given the following files: main.cpp Classes.h Classes.cpp The current implementation outputs: Shape Colour: Red Shape Area: 0 Shape Colour: Blue Shape Area: 0 Change the code to use polymorphism and virtual functions to enable overriding of the Area function of the base class Shape to use the Area function of derived class Circle or Rectangle depending on the type of the object. The code should output: Shape Colour: Red Shape Area: 78.5397 Shape Colour: Blue Shape Area: 24 main.cpp #include <iostream>#include <vector>#include "Classes.h" int main() {std::string red = "Red";std::string blue = "Blue";Circle circle(red, 5.0);Rectangle rectangle(blue, 4.0, 6.0); std::vector<Shape*> shapes;shapes.push_back(&circle);shapes.push_back(&rectangle); for (Shape* shape : shapes) {std::cout << "Shape Colour: " << shape->GetColour() << std::endl;std::cout << "Shape Area: " << shape->Area() <<…SUBJECT: OOPPROGRAMMING LANGUAGE: C++ ALSO ADD SCREENSHOTS OF OUTPUT. Write a class Distance to measure distance in meters and kilometers. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen. Write another class Time to measure time in hours and minutes. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen. Write another class which has appropriate functions for taking objects of the Distance class and Time class to store time and distance in a file. Make the data members and functions in your program const where applicable
- Write down code that can declare a class of an employee with the properties, name and salary, and the methods, getSalary and getName, that return the salary and name of the employee respectively. Function members should be declared as prototypes only andinclude a parameterised constructor prototype to initialise with the name and salary.In C++ Define a class named Complex that will represent complex numbers. Acomplex number is a number of the forma+b*i,where, for our purposes, a and b are integers and i represents sqrt(-1).In your class, include a constructor that takes two parameters andinitializes a and b to the first and second parameter respectively, and includea constructor that takes one parameter and initializes a to the value of theparameter and b to 0. Also include a default constructor that initializes both aand b to 0. Overload all of the followind operators so that they correctly applyto the class Complex: ==, +, -, *, >>, and <<.Using your Complex class, write a program that would let the user input twocomplex numbers, and then print out their sum, difference, product, and whetherthey are equal to one another.Redo Programming Exercise 3 by overloading the operators as nonmembers of the class boxType. Write a test program that tests various operations on the class boxType. Reference: Chapter 11 defined the class boxType by extending the definition of the class rectangleType. In this exercise, derive the class boxType from the class rectangleType, defined in Exercise 1, add the functions to overload the operators +,–, *, ==, !=, <=, <, >=, >, and pre- and post-increment and decrement operators as members of the class boxType. Also overload the operators << and >>. Overload the relational operators by considering the volume of the boxes. For example, two boxes are the same if they have the same volume. Write the definitions of the functions of the class boxType as defined above and then write a test program that tests various operations on the class.
- Define a class for a type called Counter . An object of this type is used to count things. 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. Write member functions to increase the value by one (called increment ) and decrease the value by one (called decrement ), don’t let the value go below 0. Write a member function ( print ) that prints out the value of the counter.*The first photo is the driver program that you should include to test your class ****The second is what the program should look like****Use any algorithm you like for your Final Project C++. Some examples are: ATM machine Vending Machine Driving a car A simple game Your project shall use the following as a minimum: The main function that utilizes the minimum code to drive the program. Coding details shall be in appropriately-implemented classes. At least three class modules, the base class shall be abstract and two associated derived classes. At least one example of an overloaded constructor. At least one polymorphic method. Demonstrate correct use of public, private and protected keywords.Problem: Create a base class called Vehicle that has the manufacturer’s name (typeString), number of cylinders in the engine (type int), and the owner (type Person). Use thePerson class developed this semester. Create a class automobile that is derived fromVehicle and has additional properties: number of passengers (type int) and weight in tons(type double). Create a class Truck which is derived from Vehicle and has additionalproperties: the load capacity in tons (type double, since it may contain a fractional part)and towing capacity in tons (type double). The classes should have:• Two constructors, a default and an overloaded constructor• All appropriate accessor and mutator methods (getters and setters).• An ‘equals’ method (must conform to the Person example and the Object class ).• A ‘toString’ method• A ‘copy’ constructor• A ‘clone’ method• A ‘finalize’ method Write a driver (client/test) class that tests ALL the methods. Be sure to invoke each of the constructors, and ALL…
