Manage A List Of Computer-Related Problems For A Help Desk

Manage a list of computer-related problems for a help desk app

Write a program to manage a list of computer-related problems for a help desk application. This will involve creating, adding to, removing from, and displaying a linked list of "problem" objects. The data should be stored in external files: "problems.txt", "newproblems.txt", and "resolvedproblems.txt", with a format such as problem code, criticality, date, contact name, etc. The program should include a class to model a problem with data members: problem code, criticality (1-5), date, and contact name.

Create a class (ProblemList) that has an ordered linked list of Problem objects. The list should be ordered by priority, which depends on criticality (higher priority for criticality 1) and date (earlier date if criticality is equal). Overload comparison operators (

Your program should be able to:

- Read problems from the three files and populate the list.

- Add new problems and remove resolved problems using the operator overloads.

- Provide methods to output the top n and bottom n problems in the list via functions writeTop(n) and writeBottom(n).

The list clearly demonstrates the use of abstraction, encapsulation, and operator overloading; the linked list class used can remain unmodified. Use comments extensively for clarity. The program should produce output displaying the top and bottom-problems in order.

Your solution must include:

- A class definition for Problem with comparison operators.

- A templated ordered linked list (as given).

- A class ProblemList managing the list, with overloaded operators and methods.

- Main driver code that initializes ProblemList objects with file input, merges lists, removes items, and displays top/bottom problems.

Finally, your program should print:

- The list of top 25 critical problems.

- The list of bottom 25 problems, which are least urgent.

Please submit:

- A cover page with assignment name, student name, and list of attachments.

- All source code files (.cpp, .h) with comments.

- The output generated from the input files.

The code should be organized, commented, and designed following object-oriented principles.

Manage a list of computer-related problems for a help desk app

The development of an effective help desk application hinges on robust data management of problems reported, their priorities, statuses, and resolution history. A suitable approach involves leveraging object-oriented programming constructs, particularly classes, to encapsulate problem data and linked lists to organize these items efficiently in memory. The project entails implementing classes for individual problems and managing ordered linked lists, with various operator overloads to facilitate succinct list operations. The solution should support reading data from external files, updating the problem list by adding new problems and removing resolved ones, and displaying critical information such as the top priority and least urgent problems. Below is a detailed discussion of the design, implementation, and expected functionalities for such a system.

Design of the Problem Class

The core data entity is the Problem class, which encapsulates all relevant attributes of a help desk problem. Data members include:

  • Problem Code: a string or integer that uniquely identifies the problem type.
  • Criticality: an integer value from 1 (highest importance) to 5 (lowest importance).
  • Date: an object of a Date class, representing the date the problem was reported. This could be a custom class or use standard date representations.
  • Contact: a string indicating the name of the person reporting or initiating the problem.

To facilitate sorting, the Problem class must overload comparison operators (

This ordering logic is implemented by overloading the

Linked List Implementation

The linked list is implemented via a templated class, as provided, called OrderLinkedList. This class manages nodes via ListNode template class with data of type ItemType.

Using this, the ProblemList class manages an ordered linked list of Problems. The class must overload operators such as += (to merge in another list or add Problems) and -= (to remove Problems). It should also provide methods for writing the top n list and bottom n list of problems, which involves traversing the linked list from the start or the end—this can be managed either via iteration or by copying to an array or vector for reverse indexing.

File Input and Initialization

The application will initialize three ProblemList objects from files:

  • problems.txt: the current active problems.
  • newproblems.txt: new problems not yet assigned.
  • resolvedproblems.txt: list of problems that are resolved and can be removed.

The input files follow a CSV format: problem code, criticality, date (MM/DD/YYYY), contact first and last name. Parsing these files populates the respective ProblemList objects.

Operator Overloading and List Management

Overloaded operators enable efficient list management:

  • operator+=: merges another ProblemList into the current list, maintaining order.
  • operator-=: removes Problems found in another list (e.g., resolved problems).

This design models real-world scenarios, such as adding new problems to the current queue or removing resolved issues once addressed.

Output Functions

The two key functions, writeTop(n) and writeBottom(n), output the first and last n problems, respectively. This displays the most critical problems and the least urgent ones.

This could be implemented either by iterating from head for top n or reversing the list or indexing for bottom n, ensuring the output is sorted by priority and date.

Implementation Summary

The solution involves:

  1. Defining the Problem class with proper comparison operators.
  2. Using the existing templated OrderLinkedList class for the linked list structure.
  3. Creating the ProblemList class that contains an OrderLinkedList of Problem objects, overloads necessary operators, and provides the display methods.
  4. Reading data from files into ProblemList objects and performing list operations.
  5. Outputting the top and bottom lists with formatted descriptions.

Conclusion

Such an application demonstrates fundamental object-oriented principles including encapsulation, abstraction, operator overloading, and dynamic memory management. It allows efficient manipulation of organized data representing help desk problems, facilitating prioritized problem resolution and historical record keeping. Proper commenting and modular design ensure maintainability and extendibility.
