How to Print Linked List in C++? Last Updated : 23 May, 2024 Comments Improve Suggest changes Like Article Like Report A Linked List is a linear data structure that consists of nodes having a data member and a pointer to the next node. The linked list allows the users to store data of the same type in non-contiguous memory locations through dynamic memory allocation. In this article, we will learn how to print a linked list in C++. Example Input: Linked List: 1->2->3->4->5 Output: 1 2 3 4 5Print Linked List in C++To print a linked list in C++, we can follow the below algorithm: Algorithm to Print a Linked ListStartInitialize a pointer temp to point at the head of the linked list.While temp is not equal to nullptr:Print temp->data.Move temp to the next node using temp=temp->next.StopC++ Program to Print a Linked ListThe following program illustrates how we can print a linked list in C++: 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; } // Function to print the linked list void printList() { Node* temp = head; while (temp != nullptr) { cout << temp->data << " "; temp = temp->next; } cout << endl; } }; int main() { // Declare an object of the linked list class LinkedList list; // insert some values to the list list.insert(1); list.insert(2); list.insert(3); list.insert(4); list.insert(5); // Print the linked list list.printList(); return 0; } Output1 2 3 4 5 Time Complexity: O(N), where N is the number of nodes in the linked list.Auxiliary Space: O(1), as no extra space is used to print the linked list.
