Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Question

Do the whole code in C++ and please kindly share whole program.

Given a pointer to the head of a linked list and a specific position, determine the data value at that position. Count backwards
from the tail node. The tail is at postion 0, its parent is at 1 and so on.
Example
head refers to 3 → 2 → 1 → 0 –→ NULL
position FromTail = 2
Each of the data values matches its distance from the tail. The value 2 is at the desired position.
Function Description
Complete the getNode function in the editor below.
getNode has the following parameters:
• SinglyLinkedListNode pointer head: refers to the head of the list
int positionFrom Tail: the item to retrieve
Returns
int: the value at the desired position

Process by which instructions are given to a computer, software program, or application using code.

I need help with this assignment, I need to make a struct to implement a limited Python style list in C++. When you bootstrap the exercise, you will be given a main.cpp file, with a simple program written in it. The program declares a Python style list and appends several elements to it, before printing it out to the terminal. The file is where I would setup my code #ifndef PY_LIST_H #define PY_LIST_H #include <iostream> struct PyList { // Declare your vars here PyList(){ // Implement this } void append(int x){ // Implement this } void append(char x){ // Implement this } void append(float x){ // Implement this } ~PyList(){ // Implement this } }; std::ostream& operator<<(std::ostream& os, const PyList& pyList){ os << '['; // Complete this implementation os << ']'; return os; } #endif Here is the main.cpp file that it must be able to run and the float must not have floating zeros #include <iostream> #include "PyList.h"…
