Modify And Add Additional Functions To My Assignment

Modify & add additional functions to my assignment if needed

I need to modify and add additional functions to my assignment if needed. My code is working fine; however, I want to ensure everything is correct and complete. Specifically, I need to:

  • Recognize that the Client_Address_Book is a dynamic array and note the changes in the class state accordingly.
  • Set the capacity value to 27 in the default constructor of the Client_Address_Book class.
  • Implement a destructor for the Client_Address_Book class.
  • Implement a copy constructor for the Client_Address_Book class.
  • Implement a copy constructor for the Client_Info_BST class.
  • Implement a destructor for the Client_Info_BST class.
  • Change the last statement in the main function in the driver (hashing.cpp) to call Print_Hash_Table with an output filename parameter.

Below is a comprehensive review and implementation plan based on these requirements, ensuring that all necessary modifications enhance the robustness and functionality of your assignment code.

Paper For Above instruction

The programming assignment under consideration involves managing a client address book system, which is implemented with classes such as Client_Address_Book, Client_Info_BST, and possibly others. The primary objectives are to ensure proper memory management through destructors, facilitate object copying via copy constructors, and set initial parameters such as capacity. Additionally, the code requires a minor modification in the main driver file to output data appropriately. This discussion provides a detailed plan and implementation for these tasks, emphasizing best practices in C++ programming, especially concerning dynamic memory management and class design.

Understanding the Client_Address_Book Class

The Client_Address_Book is a dynamic array class, implying it manages a block of dynamically allocated memory to store client information. Because it's a dynamic array, managing the memory lifecycle is critical to prevent leaks and dangling pointers. The class's state likely includes a pointer to the array, the current size (number of stored clients), and the capacity—the maximum number of clients the array can hold before resizing. Setting the capacity to 27 in the default constructor establishes a starting point for the storage, which may later be expanded as needed.

Implementing the Default Constructor with Capacity

To initialize the Client_Address_Book class with the specified capacity, the default constructor should allocate memory for 27 client entries. The constructor will also initialize the size indicator to zero, indicating an empty address book. The code snippet might look as follows:



Client_Address_Book::Client_Address_Book() {


capacity = 27;


size = 0;


addressArray = new ClientInfo[capacity];


}

Here, ClientInfo is assumed to be a class or struct representing individual client details.

Implementing Destructor for Client_Address_Book

A destructor ensures that dynamically allocated memory is correctly released when an object of Client_Address_Book is destroyed, thus preventing memory leaks. The destructor should delete the array and set the pointer to null.



Client_Address_Book::~Client_Address_Book() {


delete[] addressArray;


addressArray = nullptr;


}

Implementing Copy Constructor for Client_Address_Book

The copy constructor allows creating a new Client_Address_Book object as an exact copy of an existing one, including deep copying the dynamic array to avoid shared pointers that could cause issues when destructors run. The implementation involves allocating new memory and copying each element from the source object:



Client_Address_Book::Client_Address_Book(const Client_Address_Book& other) {


capacity = other.capacity;


size = other.size;


addressArray = new ClientInfo[capacity];


for (int i = 0; i 

addressArray[i] = other.addressArray[i];


}


}

Implementing Copy Constructor for Client_Info_BST

Similarly, if Client_Info_BST is a Binary Search Tree managing client info, its copy constructor should perform a deep copy of the entire tree structure. This typically involves recursively copying nodes. Here's a high-level idea:



Client_Info_BST::Client_Info_BST(const Client_Info_BST& other) {


root = copyTree(other.root);


}


Node Client_Info_BST::copyTree(Node node) {


if (node == nullptr) {


return nullptr;


}


Node* newNode = new Node(node->data);


newNode->left = copyTree(node->left);


newNode->right = copyTree(node->right);


return newNode;


}

This implementation assumes the existence of a Node structure with left/right pointers and data fields.

Implementing Destructor for Client_Info_BST

The destructor must delete all nodes in the BST to prevent memory leaks, typically using a post-order traversal:



Client_Info_BST::~Client_Info_BST() {


destroyTree(root);


}


void Client_Info_BST::destroyTree(Node* node) {


if (node != nullptr) {


destroyTree(node->left);


destroyTree(node->right);


delete node;


}


}

Modifying the Main Driver (hashing.cpp)

The final task involves changing the last statement in the main function to call the Print_Hash_Table method with a filename argument, enabling output to a specified file. The code modification would resemble:



My_Book.Print_Hash_Table("output_filename.txt");

This change allows the program to output the hash table contents directly to a file, facilitating better data management and review.

Conclusion

Implementing these functions and modifications enhances the robustness, flexibility, and correctness of the client address book system. Proper memory management through destructors and deep copies via copy constructors are vital in C++ to prevent resource leaks and dangling pointers. Setting the initial capacity during object construction ensures predictable behavior and prepares the system for potential scalability. The final adjustment in the main driver file aligns with best practices for output management. These steps collectively ensure the system adheres to high standards of software engineering, promoting maintainability and reliability.
