Compile Error in VS2010 while testing LinkedLists - c++

Question

I'm doing some tests to a LinkedList, that has two pointers: one point to the next item in the list and the other point to a random node within the list.
Here is the code:
struct Node
{
Node* pNext; // a pointer to the next node in the list
Node* pReference; // a pointer to a random node within the list
int number; // an integer value
};
/**
* This version works for small/medium lists, using recursion.
*/
Node* duplicateList(Node* n)
{
if (n == NULL) return NULL;
return new Node()
{
number = n->number,
pNext = duplicateList(n->pNext),
pReference = duplicateList(n->pReference)
};
}
I'm getting the following errors (VS2010):
d:\dornad\my documents\visual studio 2010\projects\test\test.cpp(21): error C2143: syntax error : missing ';' before '{'

Thanks.

Answer 1

This bit is not valid C++:
return new Node()
{
number = n->number,
pNext = duplicateList(n->pNext),
pReference = duplicateList(n->pReference)
};
Change it to this:
Node* pNode = new Node();
pNode->number = n->number;
pNode->pNext = duplicateList(n->pNext);
pNode->pReference = duplicateList(n->pReference);
return pNode;

Answer 2

Add a constructor to Node:
struct Node
{
Node(Node* next, Node* ref, int number) : pNext(next), pReference(ref), number(number) { }
// ...
};
then
return new Node(a, b, c);
