Class project
 
Objective:
The purpose of this project is to expose you to:
Applying analysis, design and implementation of a linked list using dynamic data structure, discrete methods such as recursion are utilized in solution, objects classes are used in constructing a multi file project. RAM organization and the use of “this” pointer to accomplish tasks; in addition to using referenced parameters as constant, all methods are implemented in a procedure like programming to implement class objects and operations.
.
Problem Specification:
You are to submit the analysis, design and implementation of a bag that maintains an ordered linked list.
 
Details:
Each node’s data consists of:
id number (integer)
Name (string)
Hours & Rate both are of the same type (both are: integers, floats or doubles).
Two sets of data are provided in the attached files.
 
Your program must load the data from one of the files and place it  in a linked list, data is organized in descending order (that is highest to lowest) based on the id number as it is being loaded. To test if the program works properly load the data from the second file.
 
Each Node of the list contains the data above, and a pointer to the next node. You are to define the Node class in a specification file, and the setters and getters methods for each attribute, that will maintain the list, in a C++ implementation file.
The client C++ file will contain code that interacts with the user using a menu like interface to test operations on the sorted list. You may choose to define a child class that inherits the Node class or may use object composition. However, every class must have two files a header and an implementation.
 
Methods include but are not limited to the following:

    • Add is a method that adds a Node at its appropriate position.
    • Location is a method that returns a pointer to where action may take place. (Recursive)
    • Remove is a method that removes a selected Node if it exists, returns true or false.
    • Clear is a method that clears the list of all the Nodes, but before a Node is deleted, it calls a print method that prints the Node’s data to a file. All nodes that are created using the new operator must be de-allocated, deleted.
    • Peek is an accessor method that displays, on the screen, a Node’s data, for a given students name, if the Node with name does not exist the method will display that. The list is unchanged.
    • getGross is a private method that calculates and returns the gross (gross is not an attribute).
    • getNet is a private method that calculates and returns the net after taking 20% taxes (net is not an attribute).
    • Other functions may be used such as getData(), setNext() … as explained in the book and in previous projects.

 
Requirements:

  • Specify each method’s purpose, describe its parameters, and write a pseudo-code version of its header as explained in the book.
  • A static data member that keeps track of the number of nodes in the list.
  • Create a UML class diagram for each of the classes.
  • Use templates to accommodate employee’s payroll data that are integer, float or double.
  • Create a header file and implementation file for the bag.
  • Create a header file that contains the class declaration for the class Node. Each node contains data and a pointer to the next node. The last node’s next field should always be NULL.
  • Create an implementation file that contains the methods for each class.
  • Define a default constructor that initializes the head pointer to NULL.
  • Define a destructor, may be virtual, if deleting nodes is done in other methods.
  • Define a method to determine if the list
  • Use guards against duplication of #include.

 
Create as many  ”.h” header files as needed and write your own “.cpp” file  that is a driver containing a menu like choices to drive the project. Loading the list is not a menu option, it’s done automatically and the nodes are in order.
