In this project, y ou will be writi ng an object that implements an ordered link

Question

In this project, you will be writing an object that implements an ordered linked list with operator overload support for insertions and deletions. The specification for the list object will be provided upfront and you must design an implementation that supports the provided specification. In addition, you will be given a list of tasks that should be performed.

CIS 221 Programming II C++ Programming Project operator overloaded ordered Linked List object Overview In this assignment, the student will write a C++ program that implements an "Ordered Linked List" object with support for overloaded insertion and deletion operations implemented through an operator overload. When completing this assignment, the student should demonstrate mastery of the following concepts: Elementary Linked Data Structures Advanced Dynamic Memory Managing Multiple Entities on the Heap Software Engineering Design from Provided Object Specification Operator overloading Binary Operators Intermediate Node Insertion Algorithms Assignment In this project, you will be writing an object that implements an ordered linked list with operator overload support for insertions and deletions. The specification for the list object will be provided upfront and you must design an implementation that supports the provided specification. In addition, you will be given a list of tasks that should be performed. Here is the specification for the object that you are to build. When completing this assignment, you must adhere to the interfaces provided in this header when implementing each method You should not modify this file and use all of its components in the most intuitive way possible. Documentation is provided internally that explain what each method should do in the form of coded comments. Operator Overloaded 0rdered Linked List Specification File Author Description: This is the object specification for an "ordered Linked List overloaded operator allows element insertions. overloaded operator allows for deletions PRE-PROCESSOR #pragma once CONSTANTS const int OK const int NOT FOUND const int ERROR MEMORY -1; NODE SPECIFICATION Description: Each linked 00LNode structure contains the information for a single element in the list struct OOLNode int ayload
