Define a class "Point" with two instance variables-x and y, representing the Cartesian coordinates of the point. The class should contain a default constructor which initializes a point in the origin and a parameterized constructor which initializes a user-specified point. Create another class "Line" that inherits Point class. The class should include the instance member- a reference variable of Point class. The constructor of Line class, should create a new Point object to denote the end point of the line. The starting point of the line is automatically created when it extends the Point class. The Line class also should include calculateDistance) method to find the length of the line,, thus created. Note: distance=v((x2 - x1)" + (y2- y)) Jrite a main class that tests the above inherited class for an array of objects.

initializes a point in the origin and a parameterized constructor which initializes a user-specified point.
Create another class "Line" that inherits Point class. The class should include the instance member- a reference variable of Point class. The constructor of Line class,
should create a new Point object to denote the end point of the line. The starting point of the line is automatically created when it extends the Point class. The Line
class also should include calculateDistance() method to find the length of the line, thus created.

Implement a nested class composition relationship between any two class types from the following list: Advisor Вook Classroom Department Friend Grade School Student Teacher Tutor Write all necessary code for both classes to demonstrate a nested composition relationship including the following: a. one encapsulated data member for each class b. inline default constructor using constructor delegation for each class c. inline one-parameter constructor for each class d. inline accessors for all data members e. inline mutators for all data members
Model a room class, whose member data is three integers length, width and height. The classcontains two constructors to initialize the room class objects, first is no argumentconstructor, while the second in three arguments constructor. Class also contains threemember functions i.e., getdatat) to get the data from user and store in the memory of callingobject and showdata) to show the room data of calling object, int volume(int I, int w, int h)function should receive the length, width and height values from the objects one by one andreturn the volumes of the three objects respectively.Write a main program to declare the three object rl, 12, and 13 of room class. Two objectwill store the values through three argument constructor and third object will get the datafrom user by calling getdata function. Then all three objects should call the volumefunctions to calculate their volumes and store them in three variables of type integer. Finallythe system compare the three volumes values…
Object 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 reference 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.
You will define three objects class Person, BookAuthor, and Book. Class Person involves a person's identity. Class BookAuthor involves a collection of books or book titles. Class Book involves the number of books in stock , book title and price. Design the three classes: The classes must use an appropriate inheritance relationship. Each class must have a constructor. Each class has at least two private data members and you must include accessors. You must test your classes by creating a BookAuthor object and printing the Person, Book and BookAuthor values from a function you create inside of BookAuthor. Make sure you use the book object correctly and put it inside of BookAuthor. in pytgi
Consider a class "Fan" with two integer data members, "state" (0/1 i.e. on or off) and "speed". 1. Write a parameterized Constructor for this class. 2. Write a member function "changeState( )" which behaves similar to pressing a button i.e. it should change the state of the fan. If it is off (0), calling the function should turn it on (1) and vice versa.. Multi Line Text.
