- Consider a class named Calculator with typical four specific functionalities i.e. addition, subtraction, multiplication, and division. Implement these functionalities as four functions with two parameters. It is also required to overload all these functions for int and double data types. In the main function, create an object of class Calculator and invoke its member functions while passing parameters of int and double type.Solve the problem in C++ (Extend MyPoint) In Programming Exercise 9.4, the MyPoint class was created to model a point in a two-dimensional plane. The MyPoint class has the properties x and y that represent x- and y-coordinates, two getter functions for x and y, and the function for returning the distance between two points. Create a class named ThreeDPoint to model a point in a three-dimensional space. Let ThreeDPoint be derived from MyPoint with the following additional features: - A data field named z that represents the z-coordinate.- A no-arg constructor that constructs a point with coordinates (0, 0, 0).- A constructor that constructs a point with three specified coordinates.- A constant getter function that returns the z value.- A constant distance(const MyPoint&) function to return the distance between this point and the other point in the three-dimensional space. Draw the UML diagram for the classes involved. Implement the classes. Write a test program that creates two…Create parent class Shapes with protected parameters width and height and function printarea() and a virtual function cal_area(). Create two sub classes Rectangle and Sqaure. In main() create 2 pointers of Shapes and assign Rectangle and Square to it. Call printarea function with the pointers. Note: Use C++ language with well explaination. After performing this program. Implement this program using an abstract class.
- Computer Science Write the definition of the class template ArrayListType, and the derived class unordered ArrayListType. Provide implementations for the non abstract functions in the base template class, and implementations of the template functions in the derived template class. Write a test program to test the functions in the derived template class. Instantiate objects of type derived class in your test program using template parameters of type float, int.What is polymorphism? Be sure to include what role virtual functions play in this and the difference between a virtual and pure virtual function. Be sure to include the defininition of an abstract base class.Writing in C++, using <iostream>, using (Pointers), (Concrete and abstract class), (Overloaded functions and constructors), (Inheritance), (Polymorphism), Write a program that user can add lists of ordered food, then user give program information if ordered food delivered, then program shows inventory(delivered food) and food that did not delivered yet.
- C++ Shape is an abstract class with a pure virtual function: Area(). (2) Circle is inherited from Shape, with a data member Radius, and a member function Area() to get the area of a circle. (3) Triangle is inherited from Shape, with two data members Bottom-length and Height, and a member function Area() to get the area of a triangle. Please complete the definition of Shape, Circle and Triangle, and define other necessary functions, to let a user can use Shape, Circle and Triangle as follows: void main( ) { Shape* p = new Circle(2); cout << "The area of the circle is: " << PrintArea(*p) << endl; Triangle triangle (3,4); cout << "The area of the triangle is: " << PrintArea(triangle) << endl; delete p; } The outputs: The area of the circle is: 12.56 The area of the triangle is: 6 //Your codes with necessary explanations: My code:…write a class implementation using C++ from the given class diagram TAKE NOTEOF THE FF SPECIFICATIONS: Using the constructor, create three objects from class Voters and store it in the stack memory. Two voters must have an active account and one voter has a deactivated account. Please note that the deactivated voter account must be still part of the “object”. Test all the functions by making calls. this should be the sample result. Please use simple codes only.We have a parking office class for an object-oriented parking management system using java Add (implement )a function to the Parking Office class to return a collection of customer ids (getCustomerIds) using java I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....). N.B. Parking office methods in the class definition like register, getcustomer and addcharge have already been implemented, we just need an additional getcustomerID function as mentioned above Explain the code you wrote with a few words
- Learning from the "Pointers-Inheritance and Dynamic Polymorphism" and "Pointers and Dynamic Memory - new - delete" example code in the files above, create three classes that exhibit dynamic polymorphism using the functions area(), circumference(), and draw(): Polygon Class Superclass Variables: double width double height Polymorphic Member Functions: area() circumference() draw() Rectangle Class Subclass of Polygon Variables: int size = 5 double* history_width_ptr double* history_height_ptr Constructor/Destructor Constructor creates space in free memory for two arrays that can store previous values of width and height: history_width_ptr = new double[size] // allocate new memory to previous width values history_height_ptr = new double[size] // allocate new memory to previous height values Destructor delete[] history_width_ptr delete[] history_height_ptr Regular Member Functions: set_values() Sets values for height and width based upon user input Then stores…By using pure virtual functions, create a simple “shape” hierarchy in C++: a base class called Shape and derived classes called Circle, Square, and Triangle. In the base class, make a virtual function called draw( ), and override this in the derived classes. Make a pointer of Shape and objects of derived class and call draw( ) through the base-class pointers, to verify the behavior of the virtual function.Write a program in the C++ language to create a class Rectangle with two member integer variables length and breadth. Write the parameterized constructor for the class and also add a member function that displays the area of the rectangle in the output.
