NULL printing a value 0xbf940000 and not a zero

hello all,
in the following code a -> next should print zero, but it is giving the output as 0xbf940000

Code:
#include<iostream.h>
#include<conio.h>
#include<stdio.h>
class Node
{
   public:
   int data;
   Node *next;
   Node(int n=1)
   {
    data=10;
    next=0;
   }
};
void main()
{
 Node *a;
 clrscr();
 a=new Node();
 cout<<a->data<<endl;
 cout<<a->next<<endl;
 getch();
}

XPath::Node(3)						User Contributed Perl Documentation					    XPath::Node(3)

NAME
XML::XPath::Node - internal representation of a node API
The Node API aims to emulate DOM to some extent, however the API isn't quite compatible with DOM. This is to ease transition from XML::DOM programming to XML::XPath. Compatibility with DOM may arise once XML::DOM gets namespace support. new Creates a new node. See the sub-classes for parameters to pass to new(). getNodeType Returns one of ELEMENT_NODE, TEXT_NODE, COMMENT_NODE, ATTRIBUTE_NODE, PROCESSING_INSTRUCTION_NODE or NAMESPACE_NODE. UNKNOWN_NODE is returned if the sub-class doesn't implement getNodeType - but that means something is broken! The constants are exported by default from XML::XPath::Node. The constants have the same numeric value as the XML::DOM versions. getParentNode Returns the parent of this node, or undef if this is the root node. Note that the root node is the root node in terms of XPath - not the root element node. to_sax ( $handler | %handlers ) Generates sax calls to the handler or handlers. See the PerlSAX docs for details (not yet implemented correctly). MORE INFO
See the sub-classes for the meaning of the rest of the API: o XML::XPath::Node::Element o XML::XPath::Node::Attribute o XML::XPath::Node::Namespace o XML::XPath::Node::Text o XML::XPath::Node::Comment o XML::XPath::Node::PI perl v5.18.2 2003-01-26 XPath::Node(3)
