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:

- For the following four classes, choose the correct relationship between each pair. public class Room ( private String m type; private double m area; // "Bedroom", "Dining room", etc. // in square feet public Room (String type, double area) m type type; m area = area; public class Person { private String m name; private int m age; public Person (String name, int age) m name = name; m age = age; public class LivingSSpace ( private String m address; private Room[] m rooms; private Person[] m occupants; private int m countRooms; private int m countoccupants; public LivingSpace (String address, int numRooms, int numoccupants) m address = address; new int [numRooms]; = new int [numOceupants]; m rooms %3D D occupants m countRooms = m countOccupants = 0; public void addRoom (String type, double area)Bookstore class uses a dynamic array to hold names book titles. class BookStore { public: BookStore (); BookStore (const Bookstore & b); // POST: object made from b -BookStore (); void insert(string title); // POST: add title to the end of the titles list private: string store; int capacity; int size; }; Describe two different situations in which the copy constructor function is called. Write a short code snippet illustrating each situation. Explain the problem if this class did not provide a deep copy constructor function. // POST: empty object with room for 10 titles // POST: object is destructed // pointer to dynamic array of book titles // capacity of array // number of books used in the bookstorepublic class date { private int day; // from 1 to 31 private int month; // from 1 to 12 private int year; // from 2000 upwards public void advance (); // move to next day }; Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000. Implement setters for day, month, and year. Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.
- PROGRAMMING LANGUAGE: C++ SUBJECT: OOP Task: Suppose you have a class Rectangle with data members width and height. The public member functions of class Rectangle are as follows: setValues(int w, int h); // to set values of width and height of objects of Rectangle class int Area();// to find area of an object of rectangle class biggerRectangle(Rectangle A, Rectangle B); prints the rectangle details which is bigger. Sample Code for passing object to a function is given below: #include <iostream> using namespace std; class CRectangle { int width, height; public: void set_values (int, int); int area () {return (width * height);} void copyData(CRectangle rect); }; void CRectangle::copyData(CRectangle rect) { width=rect.width; height=rect.height; cout<<"width of c = "<<width<<", height of c= "<<height<<endl; } void CRectangle::set_values (int a, int b) { width = a; height = b; } int main () { CRectangle a,b,c;…class displayClass{public:void print();...private:int listLength;int *list;double salary;string name;} Write the definition of the function to overload the assignment operator for the class displayClass.There is a member function with the same name as the class called A(n) .
- Object oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…in c++ write aprogram to Create a class Rectangle with length and breadth as private data members and also provide the following member functions: getdata(): gets the length and breadth of rectangle. calarea(): return the area of the rectangle. calperi(): return the perimeter of the rectangle. issquare(): return true if the rectangle is square1- A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b). The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.
- There are two types of data members in a class: static and non-static. Provide an example of when it might be useful to have a static data member in the actual world.class GradedActivity { private: double score; public: GradedActivity() { score = 0.0; } GradedActivity(double s) { score = s; } void setScore(double s) { score = s; } double getScore() { return score; } char getLetterGrade() const; }; Implement the GradedActivity class above. In this C++ assignment, create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score: functionality (max 50 points), efficiency (max 25 points), and style (max 25 points). Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style. Signature: void Assignment::set(int, int, int) Create a main program which instantiates an Assignment, asks the user…One use of the this pointer is to access a data member when there is a local variable with the same name. For example, if a member function has a local variable x and a data member x, then you can refer to the data member as this->x. Use this fact to complete the constructor implementation of this Point class: class Point { public: Point(int x, int y); int get_x() const; int get_y() const; private: int x; int y; }; Not all lines are useful.
