So form code should be established in a functional way and outcome also. Implement the class Point3D. Put the class definition in the header p1.h and the implementation in the p1.cpp file. You may not have anyinline functions defined in the header file. Use the file xercise.cpp to check if your implementation is syntactically correct.• The class has three data members: x, y, and z, which are double.• The default constructor initializes the Point3D to the origin (0, 0, 0), while the working constructor supplies values for x, y, and 2:all doubles in that order.• Create accessors getX(), getY() and getZ(). There are no mutators. (The class is immutable)•Write a member function distance() that returns the distance between the current Point3D (the implicit parameter which will bethe left-hand side of an expression) and a second Point3D passed as an explicit parameter (which will be the right-hand-side of theexpression). Here is the distance formula for a 3D point:(x₁-x2)² + (y₁ - y₂)² + (Z₁-Z2)²You must both define and implement a feature for the tests to run. For instance, if you define getX() but fail to implement it, then yourcode will not compile. If your code fails to compile, comment out both the definition and the implementation of the feature that fails.Exam C++ Quick Reference1.cpp1#include 2#include 3 #include 4 #include 5 #include 67 #include "p1.h"89 // Implement your member functions in this fileSENAZAS=28=AAZAAZA10 Point3D Point3D()11 {1213 }141715 Point3D:: Point3D(double xx, double yy, double zz)16 {18192921using namespace std;2423 {22 double Point3D :: getX()return x;2625 }29}303127 double Point3D :: getY()34{x=y=z= 0;}33 {X = XX;y = yy:z = 22;32 double Point3D::get()35 }return y;return z;

Define a Pet class that stores the pet's name, age, and weight. Add appropriate constructors, accessor, and mutator functions. Also define a function named getLifespan that returns a string with the value “unknown lifespan." Encapsulate this "Pet" class in its files of interface (pet.h) and implementation (pet.cpp). Next, define a Dog class in separate files (dog.h and dog.cpp) that is derived from Pet. The Dog class should have a private member variable named breed that stores the breed of the dog. Add mutator and accessor functions for the breed variable and appropriate constructors. Redefine the getLifespan function to return "Approximately 7 years" if the dog's weight is over 100 pounds and "Approximately 13 years" if the dog's weight is under 100 pounds. Define another Rock class in separate files (rock.h and rock.cpp) that is derived from Pet again. Redefine the getLifespan function to return "Thousands of years". Finally, write a test program that creates instances of pet rocks…

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
Create a class employee with the data members,name,id and salary as private data member . Create array of objects for four employee.compare their salary using operator overloading,and display the records of the student who is getting less salary. By c++ language.
Add a member function having return type boolcalled isOversize( ) to the publication class. Let’s say that a publication is Oversized if it has pages more than 550. You can access this function from main() using the objects created and display the string “Oversized” or “Not Oversized” for oversize/not oversized publication. Use the return value of the function to display the specified string.(use if … else…).
IN C++ Create a parent class for Student class. Parent class should be named HUMAN. Add at least 2 attributes to HUMAN class. Test your code by creating an instance of Student filling all attributes (including attributes in parent class). Print all the information using the proper function (as in previous activities). A screenshot showing the code in Visual Studio and the output (on the console screen).
shows the complete anagram.cpp program. Use a class to represent the word to be anagrammed. Member functions of the class allow the word to be displayed, anagrammed, and rotated. The main() routine gets a word from the user, creates a word object with this word as an argument to the constructor, and calls the anagram() member function to anagram the word.
1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.
Write a Program in java to define a Student class, with member variables String name; int cms String DegreeProg Make a default constructor, Make a parameterized constructor.

A C++ assignment Implement the GradedActivity class. Copying from the pdfs is fine. Create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score: functionality (max 50 points), efficiency (max 25 points), and style (max 25 points). Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style. Signature: void Assignment::set(int, int, int) Create a main program which instantiates an Assignment, asks the user for its functionality, efficiency, and style scores, and prints out the score and letter grade for the assignment. ___________________________________________________ Examples from the pdfs: d PassFailExam::set(int q, int m, int p) { double numericScore, pointsEach; numQuestions =…
