#include<iostream>
using namespace std;

class node
{
public:
    int data;
    node* next;

    node()                  //default constructor
    {
        data = 0;
        next = NULL;
    }
    node(int value)         //parameterize constructor
    {
        data = value;
        next = NULL;
    }
};


int main()
{
    node* n = new node();   //no argument
    cout<<n->data<<"->";
    node* n1 = new node(1); //1 argument
   cout<<n1->data<<"->";
   node* n2 = new node(2);
   cout<<n2->data;

    cout<<endl;
    cout<<endl;


    return 0;
}

I want to make link list with different constructor.I am not understanding what should I do in constructor where I gave next = NULL.problem my next pointer is NULL everywhere.It’s not pointing any other block.
