Create Linked List In C++

#include <iostream>

// Define the structure for a singly linked list node
struct Node {
    int data;
    Node* next;

    Node(int value) : data(value), next(nullptr) {}
};

// Define the Linked List class
class LinkedList {
private:
    Node* head; // Pointer to the first node in the list

public:
    LinkedList() : head(nullptr) {}

    // Function to insert a new node at the end of the list
    void insert(int value) {
        Node* newNode = new Node(value);

        if (!head) {
            head = newNode;
        } else {
            Node* current = head;
            while (current->next) {
                current = current->next;
            }
            current->next = newNode;
        }
    }

    // Function to display the elements of the list
    void display() {
        Node* current = head;
        while (current) {
            std::cout << current->data << " -> ";
            current = current->next;
        }
        std::cout << "nullptr" << std::endl;
    }

    // Destructor to free memory
    ~LinkedList() {
        Node* current = head;
        while (current) {
            Node* next = current->next;
            delete current;
            current = next;
