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:
![Suppose that we have the following class:
1 class Book{
2 private:
3 int id;
4 char name [20];
5 float price;
6 int year;
7 public:
8 //constructors
9 //set and get member functios
10 };
Implement the member functions setName and
setYear](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F04acbbee-b7e8-4cd0-a50f-1bcc286fe2fe%2Fa60afe2d-4801-4b68-8ced-c45b71f80d36%2Fditr79_processed.jpeg&w=3840&q=75)

Demonstrate the classes by writing a program that uses a production worker object . note: please submit 3 files employee.h productionWorker.h cpp fileIn 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.
- Define a class called student that has thefollowing data members: - int student number- string student name- double student averageThe following member functions:- Constructor that initialize the datamembers with default values. - set and getfunctions for each data member- Print function to print the values of data members.Activity - Abstract Class An English teacher wants to find assessment mark of all the students in his course. Write a java program to find assessment mark of the students using following instructions. Save the project/file as StudentAbstract. A) Abstract Class name: Assessment Abstract Member Method: - to calculate and return total score totalScore() B) Class name: English extends Assessment Member variables: QuizMark, PracticeTest, ListeningMark Member Method : - Constructor to initialize member variables - to calculate and return total score totalScore QuizMark + PracticeTest*0.25 + %3D ListeningMark/2 C) Controlling class : StudentAbstract - To create an object of English class - To print totalScore of the EnglishC++ 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 the Member class, complete the function definition for SetNumPoints() that takes in the integer parameter newNumPoints. Ex: If the input is 4.5 62, then the output is: Height: 4.5 Number of points: 62 3 4 class Member { 5 6 7 8 9 10 11 12 17 } 1's public: void SetHeight (double newHeight); void SetNumPoints (int newNumPoints); 13 20 21 } double GetHeight() const; int GetNumPoints() const; private: 13 }; 14 15 void Member::SetHeight (double newHeight) { height= newHeight; 16 double height; int numPoints; ce es erabyCamScanner ur numPoints = newNumPoints;There is a member function with the same name as the class called A(n) .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.
- Write a class Circle with the following properties and place the class in a separate header file: • Data Members • Radius • Center x location • Center y location Member Functions • Set and Get functions for all data members • Area function that returns the area of the circle • Distance function that has a single parameter of another Circle and returns the distance between the two circles Three parameter constructor (radius, x, y) Write a program that includes the Circle header file, constructs two different circles and demonstrates the area and distance functions.c++ Build a class Sale with private member variablesdouble itemCost; // Cost of the itemdouble taxRate; // Sales tax rateand functionality mentioned below:● Write a default constructor to set the member variable itemCost to 0 andtaxRate to 0. ● Write a parameterized constructor that accepts the parameter for eachmemberSale( double cost, double rate) ● Generate only accessors for itemCost and taxRate● Write a function double getTax( ) to calculate tax i.e take a product ofitemCost and itemRate. ● Write a function double getTotal( ) to calculate the total price of itemi.e. take a sum of itemCost and getTax( ) (calling getTax() will returnthe calculated tax on item).Define a class called graduatestudent that inheritsdata members and functions from the class student,and then declare the following data members :- int level- int yearMember functions:- constructor -set and get functions for each data member- Print function.
