//cant get rid of the zero

#include <stdlib.h>

#define MAXNODES 3

typedef struct node
{
    int val;
    struct node* next;
}node;


int main(void)
{
    node* first, *newn;
    int x = 0;

    first = malloc(sizeof(node));
    first->next = NULL;
    
    newn = first;    
    
    //this initializes the nodes with data 1-whatever
    for(int i = 0; i < MAXNODES; i++)
    {
        newn->next = malloc(sizeof(node));
        newn->val = x + 1;
        newn = newn->next;
        newn->next = NULL;
        
        x++;
    }

	newn = first;

    printf("\n\n");


    while (newn)
	{
	    printf("node value: %i\n", newn->val);
	    newn = newn->next;	    
	}



return 0;
