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:

- 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.If a derived class redefines a member function inherited from the base class, for example a printInfo function, the derived class can call the base class's version of the function but it needs to use what operator to do so?please assist me c++ language 1, employee and productionwork classes design a class named employee. the class should keep the following information: employee name employee number hire date write one or more constructors, and the appropriate access and mutator functions, for the classes. next write a class named production worker that is derived from the employee class. the product ionworker class should have member variables to hold the following information shift (an array) Hourly pay rate (a double) the workday is divided into two shifts: day and night. the shift variable 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 one or more constructors, and the appropriate accessor and mutator functions, for the class. Demonstrate the classes by writing a program that uses a production worker object . note: please submit 3 files employee.h productionWorker.h cpp file
- The distinction between a class's static and non-static data members is as follows: Give an example of real-world application where you think a static data member would be useful.C++ You may work on a single class. The parameter and return type s of each function and class member function should be decided in advance. The program will be best implemented as a multi-file program, (header file, the main program,..) Design a generic class to hold the following information about a bank account: Balance Number of deposits this month Number of withdrawals Annual Interest Rate Monthly service charges The class should have the following member function: Constructors Accepts arguments for the balance and annual interest rate. deposit a virtual function that accepts an argument for the amount of the deposit. The function should add the argument to the account balance. It should also increment the variable holding the number of deposits. withdraw a virtual function that accepts an argument for the amount of the withdrawal. The function should subtract the argument from the account balance. It should also increment the variable…If a base class has a virtual member function named check(), and a pointer variable ptr of that class is pointing to a derived object, then the code ptr->check(); calls the derived class check function if it is defined.
- Using c++ create a class with a static member item so that when ever a new object is created the total number of objects of the class can be reported.C++ 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.Explain why memberwise assignment in a class with a pointer member may cause problems.
- Language=C++ Create an employee class. The member data should comprise an int for storing the employee number and a float for storing the employee’s compensation. Member functions should allow the user to enter this data and display it. Write a main() that allows the user to enter data for three employees and display it (Use Array of objects).Using C++ programming language in object oriented programming in C++ concept Create a class called time that has separate int member data for hours, minutes, and seconds.One constructor should initialize this data to 0, and another should initialize it to fixedvalues. Another member function should display it, in 11:59:59 format. The final member function should add two objects of type time passed as arguments.C++ create a class with a static member item so that whenever a new object is created the total number of objects of the class can be reported.
