Linked List C

Hello all

I don't know if anyone here codes in C, but I've been looking at this code for days and I am struggling to find out what's wrong.

I'm trying to create a simple linked list with a for loop, after which I print it out, but when I print it out the value that is printed is "3" as opposed to "1, 2 3". Here is my code

#include<stdio.h>
#include <alloca.h>


typedef int DATA;
struct Node
{
    DATA d;
    struct Node *next;
};




int printList(struct Node **head)
{

    struct Node *newNode = (struct Node *)malloc(sizeof(struct Node));
    struct Node *temp;
    temp = *head;
   while(temp!=NULL)
   {
       printf("%d \n", temp->d);
       temp = temp->next;

   }

    return 0;
}




int main()



{
    struct Node *newNode = (struct Node *)malloc(sizeof(struct Node));
    struct Node *head = newNode;
    struct Node *temp = newNode;
    head->d = 1;
    int i = 0;
    printf("Enter 3 numbers");


    for( i = 0; i< 3; i++)
    {
        scanf("%d", &temp->d);
        temp->next = newNode;
        temp = temp->next;

    }

    temp->next = NULL;
    printf("%d \n", temp->d);

    return 0;

}
