I want Python Code. Implement the Python Inheritance, the core object-oriented programming concept. You are here required to develop a University Management System (UMS) to handle day to day activities of Students, Faculty and Finance Department. Create a parent class named “person” with following attributes: Name, Surname and Registration_Number. Create a child class named “student” derived from parent class “person”. It will have same attributes as parent class: Name, Surname and Registration_Number. In addition, it will have a Boolean attribute “student_type”. It can be undergraduate or postgraduate. In addition, it will have a list attribute “current_courses”. Initially, keep it empty. Create a method named “Add_Course()” to append the courses he/she is taking. In addition, it will have attribute named “Fees”. Initially, keep it empty. Create a method named “Fees_Calculator() to calculate the current fees of the student member. Each undergraduate student pays 500 per course,…
Java Assignment: Experiment with naming rules in Java Does the language use static or dynamic scoping? Can scopes nest? Are they open or closed? Does the scope of a name encompass the entire block in which it is declared, or only the portion after the declaration? How does one declare mutually recursive types or subroutines? Can subroutines be passed as parameters, returned from functions, or stored in variables? If so, when are referencing environments bound? Justify your answers with suitable code snippet and its output.
Profile the performance of the memoized version of the Fibonacci function defined in Project 6. The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counterclass is passed as a parameter, the countproperty of that instance should be incremented based on the number of recursive calls. The __str__ method should return the countproperty's value as a string. Please can you change the solution to this problem here, because this is wrong. """ File: fib.py Project 11.7 Employs memoization to improve the efficiency of recursive Fibonacci. Counts the calls and displays the results.

Practice overriding. In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. We build another toString function to override the other one that also prints out the make, model, and odometer reading for a vehicle object. Reuse your Car class in the last exercise. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */…

CS 232 - Lab #6 - Pets Ahoy! We have recently been discussing the creation of classes in C++. Recall that classes serve as a "template" for the objects in our program, and that when we instantiate a class, we are creating an object which models the properties and behaviors of real-world objects. For this assignment, design and implement a parent class to represent a pet and several small sub-classes of the most common pets for cats, dogs, birds, and turtles. Each pet object is characterized by a type, name, birth date, owner, weight, sex, speak, and color. The variable data type for the type variable is a string that identifies the type of pet as a "dog", "cat", "bird", "turtle". The name is a string that identifies the name of the pet. The owner variable is a string that designates the name of the pet's owner. The weight specifies the pet's weight in pounds and is a double value. The speak variable is a string that holds an onomatopoeia of the sound the animal makes when it “speaks”…
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 <<…
3. Write Python code to define the Ellipse class with a reasonable number of properties and methods. For this assignment, we are learning about inheritance. For the first question, I created a class Circle to inherit from the parent class, Ellipse, using pass.
