Implement insertion of node at any position in liked list in C++

Code

#include <iostream>

using namespace std;

class Node
{
public:
    int data;
    Node *next;
};

void insertany(Node **head, int data, int position)
{
    Node *newnode = new Node();
    newnode->data = data;
    newnode->next = NULL;
    if (*head == NULL)
    {
        *head = newnode;
        return;
    }
    Node *current = *head;
    if (position == 0)
    {
        newnode->next = current;
        *head = newnode;
        return;
    }
    for (int i = 0; i < position - 1; i++)
    {
        current = current->next;
    }
    newnode->next = current->next;
    current->next = newnode;
}

void printlist(Node *head)
{
    while (head != NULL)
    {
        cout << head->data << " ";
        head = head->next;
    }
}

int main()
{
    Node *head = NULL;
    
    insertany(&head, 1, 3);
    insertany(&head, 4, 0);
    insertany(&head, 2, 2);
    insertany(&head, 6, 1);
    insertany(&head, 2, 4);

    printlist(head);
}

Output

4 6 1 2 2
