- Write definition for a class named circle with attributes center and radius, instantiate circle object that represents a circle with its center at (125, 90) and radius 65 .write function named point_in_circle that takes a circle and a point and returns true if the point lies in or on the boundary of the circle , in c++ languageCall the virtual function for an object of each of the derived class. Now call it for the object of the base class. Subject: object oriented programming Language:C++Define Object .
- Call the virtual function for an object of each of the derived class. Now call it for the object of the base class. Subject:object oriented programming Language:C++46. It is an advanced concept in Object Oriented Programming that is achieved by separating the use of a method from its implementation. Abstraction Polymorphism None of the Choices Classes Give an explanation for the answer. Thank youObject passing checklist1. Go over each member function and add the const keyword after their declaration ifthey do not modify any of the class' member variables.2. When accepting objects as parameters, prefer to pass them by reference. Add areference declarator (&) before the identifier name of an object parameter.3. If the member function does not modify the parameter, make the parameter constantby using the const keyword. apply the Object Passing Checklist. Modify food.h and volunteer.h to useobject references. Add const and & keywords in the appropriate places of the code.
- C++ Assignment---This is an unfinished code please complete it. Make changes if necessary. Upvote for finished working code. Objectives • To apply knowledge of classes and objects Instructions Implement all of the following, each in a separate Visual Studio project (and/or solution). 1. Define a class called CounterType to implement a simple counter. The class must have a private field (data member) counter of type int. You must also provide methods (member functions), including the following: a. A constructor to set the counter to the value specified by the user b. A constructor to set the counter to 0 c. A method to allow the user to set the counter to a value they specify d. A method to increment the counter by 1 e. A method to decrement the counter by 1 Your code must ensure the value of counter is never negative. If the user calls a method to attempt to make the counter negative, set the counter to 0 and print out an error to the user (e.g., “The counter must not be negative.”) Do…Topic: C# Write the C# program with explaining the proper logic used and screenshot of the output which you got in Visual Studio... Difference between static and Instance class in C# Create some classes which implement the concept of method overloading and overriding. Read on difference between Abstract class and Interfaces and find out the example when to use what? Create classes with example of Abstract class and Interface.Computer Science Object Oriented Analysis and Design. Look at the problem described below and describe how you would break it into objects, consider ways to use inheritance and composition. Describe for me how those objects make a system of objects that solves the problem. You may use UML or just write out a list of classes describing their properties and interface. You should also include a short description of how those objects work together. A local travel agent has built a business on using their knowledge of Europe to create custom trips for couples around Europe. For each client they create customized itineraries (a planned route or journey) and book all the travel and lodging accommodations for their high-end clients. For example they might build a custom vacation in Scotland where the client flies into St. Andrews and stays at a castle for 1 night then takes a bus to Pitlochry where they stay at a hotel for 3 nights then take a private plane to Braemar where they stay in a…
- oop using c++ please give me full naswer thanks Design a class named Person and its two subclasses named Student and Employee. Design two more classes; Faculty and Staff and inherit them from Employee. The detail of classes is as under: A person has a name, email address, phone number and address. A student has a status (String). An employee has an office, salary, and date hired A faculty member has office hours and rank A staff member has a title. Create display method in each class. Also create getter, setter and default constructor in above task.This is an object oriented programming question The code should be in C++ language. Design a class named Staff that includes A data member named staffID A setter function to initialize staffID A getter function to get the value of staffID Derive a class named Professor inherited from Staff class and contains Two additional data members i.e. departmentID and departmentName A parameterized constructor to initialize its own data fields along with the inherited data field Two getter functions that return the departmentID and departmentName, respectively Derive a class named VisitingProfessor inherited from class Professor and has A data field named no_of_courses A data field named salary_per_course A function named totalSalary that returns total payment for all courses (i.e. no_of_courses * salary_per_course) A member function named display to show total salary and the number of courses he/she has been taught In the main() function, create an object of VisitingProfessor and…Assume different members and methods of a real world class is grouped or embedded into a single element.
