How to Print Linked List in C++?

// C++ Program to demonstratre how to Print a Linked List
#include <iostream>
using namespace std;

// Node definition
class Node {
public:
    int data;
    Node* next;

    Node(int val)
    {
        data = val;
        next = nullptr;
    }
};

// Linked List definition
class LinkedList {
private:
    Node* head;

public:
    LinkedList() { head = nullptr; }

    // Function to add a node at the end of the list
    void insert(int val)
    {
        Node* newNode = new Node(val);
        if (head == nullptr) {
            head = newNode;
            return;
        }
        Node* temp = head;
        while (temp->next != nullptr) {
            temp = temp->next;
        }
        temp->next = newNode;

        }
        cout << endl;
    }
