rite a simple C++ code I am a beginner. Subject: Object oriented programming Write a program that has an abstract base class. This class should have four member data variables and a pure virtual function. It should also have a method for setting the data variables. Derive a class from Base class and override a method in the base class. Write a main function that creates an object of derived class and sets the variables. Also write a top-level function that will take a parameter of type base class and return the value of the appropriate (override) function.

Write a program IN C++ to model a student class with roll number and name as the sensitive information. Initialize default values for the sensitive information using a default constructor, use a copy constructor to copy from another object, use a member function to take user input and update the name and roll number and display the same using another member function. b.Add constructor overloading to the above code and enable initialization of name, roll number via constructor arguments.

We discussed in the class that during the design, you may need a class that serves as an interface for its derived classes, but you would not create any instance of that class. Such a class is called an abstract class. The UML class diagram shown below shows a class hierarchy starting from the Vehicle class which is an abstract class. Write a program to implement this class hierarchy such that the given code in the main function runs without error. Vehicle Bus Car Truck IntraCityBus InterCityBus int main() { Vehicle* V[] = { new Bus, new Car, new Truck, new IntraCityBus, new InterCityBus }; for (int i = 0; i < 5; i++) { cout<< V[i]->move() <<endl; } return 0; } Your program should produce an output as the following: Bus: Moves to carry a large number of people Car: Moves to carry a small number of people Truck: Moves to transport goods Intra-City Bus: Intra-City Bus: Moves to carry a large number of people between two areas of a city Inter-City Bus:…
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…
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.
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.
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 program in C++, that creates a class Rock with a default constructor, a copy-constructor, an assignment operator, and a destructor, all of which announce to cout that they’ve been called. In main( ), create a vector<Rock> (that is, hold Rock objects by value) and add some Rocks. Run the program and explain the output you get. Note whether the destructors are called for the Rock objects in the vector. Now repeat the exercise with a vector<Rock*>. Is it possible to create a vector<Rock&>?

WRITE A PROGRAM IN C++ Create a Circle class with a centre (x,y) and radius r. Use parameterized constructor to initialize the radius and centre of a circle object. Write a copy constructor that copies the values of one circle object to another one. Use a member function to display the values x,y,r of a circle object. Allow a friend function to update the centre and radius of the circle. There should a static variable 'number_of_circles' and a static member function 'update_number_of_circles' which will update the 'number_of_circles' whenever an instance of a circle is created. ALSO EXPLAIN
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.
Answer this in C++: In the Student.cpp file and Student.h file, build the Student class with the following specifications: Private data members string name - Initialized in default constructor to "Louie" double gpa - Initialized in default constructor to 1.0 Default constructor Public member functions SetName() - sets the student's name GetName() - returns the student's name SetGPA() - sets the student's GPA GetGPA() - returns the student's GPA Ex. If a new Student object is created, the default constructor sets name to "Louie" and gpa to 1. The output of GetName() and GetGPA() before and after calling SetName("Felix") and SetGPA(3.7) is: Louie/1 Felix/3.7 main.cpp #include <iostream> #include <vector> #include "Student.h" using namespace std; int main() { Student student = Student(); cout << student.GetName() << "/" << student.GetGPA() << endl; student.SetName("Felix"); student.SetGPA(3.7); cout <<…
Write an OOP program in C++, which contains three, classes i.e. Parent Class, Child1 Class & Child2 Class. Parent Class inherited within Child1 Class & Child2 Class. Parent Class has one member function that is Public: void Show( );. Child1 & Child2 Class will follow the signature of the Parent Class member function; each class will have different function definitions. And during running time a message will be displayed that which class object you want to create to call their member function as shown in the output below. For Example: if enter 1 then it will call parent class function If enter 2 then it will call child1 class function If enter 3 then it will call child2 class function. Hint: Solve this Program using Run Time Polymorphism.
