building 3 double linked list

[ronenk]

I need to build 3 double linked lists of numbers. It is a part of a larger program I write, which will compare elemnts of those lists. After searching thoroughly archive could not find it. This is what I wrote, but I know it's a false.
please help!

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef struct NodeStruct Node;
typedef Node *NodePointer;
struct NodeStruct{
	int value;
	NodePointer next;
	NodePointer previous;
};

NodePointer newNode (NodePointer prevNode, int value)
{
	NodePointer newNode;
	newNode=(NodePointer)malloc (sizeof(Node));
	newNode->next=NULL;
	newNode->previous=prevNode;
	prevNode->next= newNode;
	newNode->value= value;
	return newNode;
}
	

NodePointer CreateList (NodePointer head)
{
	NodePointer current;
	current = head;
	current->previous=NULL;
	current->next=NULL;
	return current;
}



void main ()
{
	Node head1, head2, head3;
	NodePointer current1, current2, current3;
	int count=0;

	/*creating emtpy list no. 1*/
	current1=CreateList(&head1);
	/*populating list 1*/
	puts ("enter an integer:");
	scanf("%d",current1->value); 
	while(current1->value!=0)
	{
		puts ("enter an integer:");
		scanf("%d",&current1->value); 
		current1->next=newNode(current1, current1->value);
		current1 = current1->next;
	}

	
	/*creating emtpy list no. 2*/
	current2=CreateList(&head2);
	/*populating list 2*/
	puts ("enter an integer:");
	scanf("%d",current2->value); 
	while(current2->value!=0)
	{
		puts ("enter an integer:");
		scanf("%d",&current2->value); 
		current2->next=newNode(current2, current2->value);
		current2 = current2->next;
	}

	
	/*creating emtpy list no. 3*/
	current3=CreateList(&head3);
	/*populating list 3*/
	puts ("enter an integer:");
	scanf("%d",current3->value); 
	while(current3->value!=0)
	{
		puts ("enter an integer:");
		scanf("%d",&current3->value); 
		current3->next=newNode(current3, current3->value);
		current3 = current3->next;
	}

}

Well, first off, this is wrong:

        scanf("%d",current3->value);

You need to pass the address of current3->value instead of the value of current3->value to scanf().

OK, code get copmiled after fixing this, but program is crashes after first integer input.

	current1=CreateList(&head1);
	/*populating list 1*/
	puts ("enter an integer:");
	scanf("%d",current1->value);

CreateList() isn't allocating memory for the node, so where is the input actually being stored?

Sometimes I just get the urge to say things like: "Yeah, that's probably bad. You should fix that."
