linked list

[susu5]

I have to write a function that takes linked list of items and deletes all repetitions from the list. but I have some errors. can you help me with the code. this is what I have tried so far!

list.h file

#ifndef _LIST_H
#define _LIST_H 

struct node {
public:
	int data;
	node * next;

public:
	void removedup();
	void insert();
	void print();
};
#endif   
 

list.cpp file

 #include<iostream>
#include"list.h"


void insert(struct node** head, int new_data);


void print(struct node *node);

struct node
	 
{

	int data; 

	struct node *next;

};

void removedup(struct node *startnode)

{

	struct node *p1, *p2, *dup;

	p1 = startnode;

	while (p1 != NULL && p1->next != NULL)

	{
		p2 = p1;



		while (p2->next != NULL)

		{


			if (p1->data == p2->next->data)

			{

				dup = p2->next;
				\
					p2->next = p2->next->next;

				free(dup);

			}

			else

			{

				p2 = p2->next;

			}

		}

		p1 = p1->next;

	}
	
	} 

main.cpp file

 #include <iostream>
#include "list.h"
using namespace std;

int main()

{

	struct node *startnode = NULL;

	insert(&startnode, 5);

	insert(&startnode, 10);

	insert(&startnode, 10);

	insert(&startnode, 15);

	insert(&startnode, 15);

	insert(&startnode, 20);

	insert(&startnode, 25);


	cout << "\n list before removing duplicates " << endl;

	print(startnode);


	 removedup(startnode);       


	cout << "\n list after removing duplicates " << endl;

	print(startnode); 


	getchar();

}

void insert(struct node** head, int new_data)

{

	struct node* new_node =
		(struct node*) malloc(sizeof(struct node));


	new_node->data = new_data;

	new_node->next = (*head);


	(*head) = new_node;

}

void print(struct node *node)

{

	while (node != NULL)

	{

		cout << node->data << endl;

		node = node->next;

	}

}

What error are you getting? compilation or run time error.
Looks like logic is ok .
