Hello, I am studying Data Structures and Algorithms, and I've been ordained by the instructor to make a recursive LinkList ADT. Well, I am almost there but still having certain problems, like I am inserting digits from 0 to 10 in the list and i am getting an extra zero at the end of traversal() function. Can anyone please help me out, here's the code:

#include<iostream>
#include<cstdlib>
#include<cstring>

typedef struct node
{
int 	data;
node*	next;
}*List;

void initialize( List X )
{
X->data = 0;
X->next = NULL;
}

void initialize( List X , List Y )
{
X->data = Y->data;
X->next = Y->next;
}

int count( List X )
{
if( X == 0 ) return 0;
return ( 1 + count( X->next ));
}

void traverse( List L )
{
if( L == 0 )
return;
else
traverse( L->next );
std::cout << L->data << std::ends ;
}

void traverse_reverse( List L )
{
if( L->next == 0 ) return;
std::cout << L->data << std::ends ;
traverse( L->next );
}

void insert( List L , int value )
{
List Temp = new node;
if( Temp == NULL )
std::cerr << "Out of Space" << std::endl;
if( L == NULL )
L = new node;

Temp->data	= value;
Temp->next	= L->next;
L->next		= Temp;
}

void remove( List& L , int value )
{
while( L != 0 && L->data == value )
{
List Tmp = L;
L	 = L->next;
delete[] Tmp;
}

if( L != 0 ) remove( L->next , value );
}

int rFind( List L , int value )
{
if( L->data != value || L->next == NULL ) return 0;
else
return 1 + rFind( L->next, value );
}

int main()
{
List x = new node;
initialize(x);
for ( int i=1; i<=10;i++ )
insert(x,i);
std::cout << count(x) << std::endl;
traverse(x);
std::cout << std::endl;
traverse_reverse(x);
std::cout << std::endl;
std::cout << rFind(x,11);
return 0;
}

Think carefully about your insert() function and what it does when L is null.

Also, it isn't the source of your problem, but just an FYI: in your traverse() function your else clause is not formatted correctly. If an else block has multiple lines, they need to be surrounded by braces (the { and } characters). The code will work as it is currently, but only by pure luck.
