In C++, create a three-level hierarchy of classes with default constructors, along with destructors, both of which announce themselves to cout. Verify that for an object of the most derived type, all three constructors and destructors are automatically called. Explain the order in which the calls are made.
Implement in C++ the necessary code to create the design part of the ADT for a Circle object using Object-Oriented Paradigm. Follow the steps of thinking about the object and designing the class in C++. Assume all the necessary attributes Assume at least the following THREE behaviors (it is up to you to add more): Your Circle object must have the following behaviors, where it can 1) ask the user and get the input regarding the diameter of the circle 2) calculate the circumference of the Circle object 3) calculate the area of the Circle object Save the design as a header file and submit it.
Declare classes Person and Student where Student is derived from Person class. Person has Name and Student has RollNo as its private member. Create a Student class object and initialize it with the already existing object of Student class. Analyze the behavior of default constructors of Person and Student classes.

only use c# sharp language! Your task here is to implement a C# code based on the following specifications. Note that your code should match the specifications in a precise manner.

Write a c++ oop code following these instructions only. Class Scene: capture_date : int draw() : void // Abstract method Class Landscape: area : double render(): void Class FlightSimulator: It has aggregation relationship with abstract class Redefine draw() function that has only a print statement of “Drawing Scene”. Class MountainScene: Call render function of Landscape as mentioned in diagram. (a) Add a function getArea() in 'Scene' class. Class Scene: capture_date : int draw() : void // Abstract method getArea() : string // Displays 'Area of Scene' Class CityScene: draw() : void getArea() : string // Displays 'Area of City Scene' Class MountainScene: draw() : void getArea() : string // Displays 'Area of Mountain Scene' (b) 1- Create a pointer of Scene class 2- Assign object of MountainScene class to the pointer created in part 1 3- Call getArea() through the pointer 4- Report the output you get in part 3
A. The members of classes can be protected by the access modifier, such as private, public, no access modifier (by default), or protected. What is the difference between public and no access modifiers (by default) in terms of packages? B.What is the relationship between the use case model and the static model for developing an object- oriented software system? C. We can implement dynamic method dispatch using inheritance or interface in Java. What is the difference between inheritance-based and interface- based dynamic method dispatch?
Write a C++ code for the problem below. Problem: Write a class called profileID, which has data members firstName, lastName, age, and birthday. Instantiate an object ECE as an object of class profileID.
Write a C++ program that implements the geometric shape “rectangle” as an object. For that, you should decide the data members that represent the object first, and then you should write the necessary member functions for the correct operation of the class. The class declaration should also include at least one constructor function. Remember that, for a rectangle, we can calculate the area, circumference, and diagonal length. You should define all member functions within the class declaration. Test all member functions written! Try to define member functions outside the class declaration.
Write a program that demonstrate the use of constructor with defaultarguments for the following problem. Define a class Person with data member as nameand age. Create three objects with no argument, one argument name and two argumentname and age. You are not allowed to create more than one constructor. using c++ language only
In C++ by using all header files and source files construct this: Create a Human class with the following features: Each Human needs a name, an age, and some phrase that they say. Each Human needs appropriate getters and setters for all attributes. For every interaction with this human, increment the age by 1 year. Default constructor with no arguments. Constructor that takes name, age, and phrase arguments. Create a driver to demonstrate all of the features of your Human class. The driver is the only class with main().The driver must create a dynamic array of Human Objects of some user defined size. This requires prompting the user for a number of Humans to create.Be sure to iterate through your array of Humans. Interact with every Human object. Demonstrate ALL features of the Human class. The Human class must to be defined in a header file with no implementation. Additionally, create an implementation file with all of the Human implementation code.
Write the program of object oriented programming c++. Declared Rectangle(Data Members: Length and width) as a friend class of Square(Data Member: int side). Thus now, all the functions of Rectangle can directly access any private member of Square.In the main function, the first statement created an object 'square' of the class Square, thus calling its constructor and assigning 5 to its data member side.The second statement in the main function created an object 'rectangle' of the class Rectangle.In the third statement, 'rectangle' called the function shape() with the object of the class Square passed as its argument. In the 'shape()' function, the value of 'side' (private data member of Square) was assigned to length and breadth. The fourth statement called the function 'getArea' of the class Rectangle.
Implement the following hierarchy using C++ classes. 1. Shape: This should be an interface class that supports area() and display() functions. 2. Circle and Rectangle: Implement the area and display functions of Shape. 3. Quadrilateral: This class should be an abstract class. It may contain member variables for length and height. 4. Trapezoid: Should inherit length, height from Quadrilateral, and add 'side', represents the side parallel to 'length'. 5. Create appropriate .h/.cpp files with constructors and destructors (wherever needed). which 6-
