How do I create three nodes with only 1 variable?

[mistersunnyd]

node 1 should be 1
node 2 should be 2
node 3 should be 3
head points to node 1

struct Node{
    int data;
    Node *next;
};
Node *h;
h = new Node;
h->data = 1;

I'm not allowed to declare another variable, yet I need three nodes for the linked list. I'm not sure how to do this.

Take a look at this

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53

#include <iostream> using namespace std; struct Node { int data; Node* next; }; // only for the 1st Node void initNode(struct Node *head,int n){ head->data = n; head->next =NULL; } void addNode(struct Node *head, int n) { Node *newNode = new Node; newNode->data = n; newNode->next = NULL; Node *cur = head; while(cur) { if(cur->next == NULL) { cur->next = newNode; return; } cur = cur->next; } } void display(struct Node *head) { Node *list = head; while(list) { cout << list->data << " "; list = list->next; } cout << endl; cout << endl; } int main() { struct Node *newHead; struct Node *head = new Node; initNode(head,10); addNode(head,20); display(head); return 0; }
