Program To Manage A Registry Of Compact D

Program 1make A Program That Manages A Registry Of Compact Discs C

Program 1: Make a program that manages a registry of compact discs (CDs). The register may e.g. be based on a doubly linked list structure according to the following approach: const int MaxLength 80; class CDNode { private: CDNode next, prev; char title [MaxLength]; char artist [MaxLength]; unsigned int time, antalspr; public: / / Constructors and destructors and member functions / / Capture, list management, file management and printing etc. } There are many other opportunities for implementation that can be used either their own variations on the above list structure or use of useful classes in the STL (Standard Template Library). Basic functionality to be included such as add and remove entries, list all existing records, etc.. The program will also be able to save the registry file and load the saved registers from file. File format eg be a simple text file format.

This paper presents a comprehensive approach to developing a C program that manages a registry of compact discs (CDs). The program utilizes a doubly linked list structure to store and manipulate CD records efficiently. Each CD record includes essential attributes such as the title, artist, total playing time, and the number of copies available. The implementation leverages standard C features, with options to incorporate features from the Standard Template Library (STL) if desired, although STL is primarily a C++ library.

The core of the program involves defining a CDNode class (or structure in C), which encapsulates data fields and pointers to facilitate list management. Key functionalities include adding new records, removing existing records, listing all CDs, and saving/loading the registry to/from a text file. These features ensure comprehensive management of the CD registry, accommodating both runtime operations and persistent storage.

Design and Implementation of the CD Registry

The foundation of the program is the CDNode structure, designed to represent individual CD entries within the doubly linked list. The structure includes the following attributes:

  • title: a character array storing the CD's title, with a maximum length of 80 characters.
  • artist: a character array storing the name of the artist, also with a maximum of 80 characters.
  • time: an unsigned integer representing the total playing time in seconds.
  • antalspr: an unsigned integer denoting the number of copies or instances available.
  • next and prev: pointers linking to the next and previous CD nodes, enabling bidirectional traversal.

This structure creates the basis for a doubly linked list, allowing efficient insertion, deletion, and traversal of CD records.

Key Functionalities

Adding and Removing Entries

The program provides functions to add a new CD record to the list, either at the beginning, end, or in sorted order based on a chosen attribute (e.g., title or artist). Removing an entry involves searching for a matching title or artist and adjusting pointer links to exclude the node, followed by deallocating memory.

Listing All Records

A function iterates through the linked list from the head, printing out the details of each CD, thus providing a comprehensive view of the registry.

File Management: Saving and Loading

Persistent storage is achieved by writing the CD registry to a text file in a simple format. Each record is stored as a line with comma-separated values for title, artist, time, and antalspr. Loading involves reading the file line by line, parsing the data, and reconstructing the linked list in memory. This allows for persistent data management across multiple program executions.

Implementation Details

The implementation is carried out in C, with necessary functions including:

  • createNode: allocates and initializes a new CD node.
  • addNode: adds a node to the list at a specified position or in sorted order.
  • removeNode: removes a node matching specified criteria.
  • listNodes: displays the list of CDs.
  • saveToFile: writes the list to a text file.
  • loadFromFile: constructs the list by reading from a file.

Input validation and error handling are incorporated to ensure robustness. Memory management is a critical focus to prevent leaks and dangling pointers.

Conclusion

Developing a CD registry management program in C with a doubly linked list offers efficient data handling and dynamic modification capabilities. Extending this program with features such as search by various attributes, sorting options, and a graphical user interface (GUI) could enhance usability further. The described design demonstrates fundamental data structure usage and file handling techniques vital for managing collections of data in software applications.
