C++ : Lecture 6: Printing / Traversing a Singly Linked List : Mastering Linked List Made Simple !

 Mastering Linked List Made Simple: Your Easy Guide to Data Structures !

Traversing / Printing a Singly Linked List Code [C++] :

#include<iostream>

using namespace std;

//Implementation of Node

class Node{

    public:

    int data;

    Node* next;

    Node(int data){

        this->data = data;

        this->next = NULL;

    }

};

// Traversing the list

void print(Node* head, Node* tail){

    Node* temp = head;

    while(temp != NULL){

        cout<<temp->data<<" ";

        temp = temp->next;

    }

    cout<<endl;

    cout<<"Head : "<<head->data<<endl;

    cout<<"Tail : "<<tail->data<<endl;

}

//Insertion at begining

void insertAtBeginning(Node* &head,Node* &tail, int data){

    // Creation of new Node

    Node* newNode = new Node(data);

    // CHeck if the list is empty

    if(head == NULL){

        head = newNode;

        tail = newNode;

        return;

    }

    newNode->next = head;

    head = newNode;

}

int main()

{

    Node* head = NULL;

    Node* tail = NULL;

    insertAtBeginning(head,tail,10);

    insertAtBeginning(head,tail,20);

    print(head,tail);

    return 0;

}
