Write a C++ function to add a node to the beginning of… (2023)

#include <iostream> using namespace std; struct Node { int val; Node *next; //it should Node instead of node }; /*Note if our list is empty then head must point to nullptr*/ void Add(Node **head, int key){ Node *temp = new Node; //Allocate memory for new node to be added temp->val = key; //assign key value temp->next = *head; //setting next of newly created node to head node to complete link *head = temp; //make newly created node head node } // main function to work correctness of Add function int main(){ Node *head = new Node; head->val = 4; head->next = nullptr; Add(&head, 2); //Now we have to pass address of head node Add(&head, 3); Add(&head, 5); Node *temp = head; while(temp->next != nullptr){ cout<<temp->val<<"->"; temp = temp->next; } cout<<temp->val<<endl; return 0; }
