have a problem with a linked list

[MrAlex]

I copied this program from the book for understanding and it doesn't work
phone.h

class phone{
public:
	char first_name[15],last_name[15];
	long number;
	phone *next;
	static int n;
	phone(const char *last,const char *first,long num);
	~phone();
	void print();
};

phone.cpp

#include <iostream>
#include "phone.h"
#include <string>
#include <process.h>
#include <iomanip>
using namespace std;
int phone ::n;
phone::phone(const char *last,const char *first,long num)
{
	if(strlen(last)<15)
		strcpy(last_name,last);
	else
	{
		cout<<"Error! the last name is too long\n";
		exit(1);
	}
	if(strlen(first)<15)
		strcpy(first_name,first);
	else
	{
		cout<<"Error!the first name is too long\n";
		exit(1);
	}
	number=num;
	next=NULL;
	n++;
}
phone::~phone()
{
	cout<<"destructing phone number"<<n<<'\n';
	print();
	n--;
}
void phone::print()
{
	cout<<setw(15)<<last_name<<setw(15)<<first_name<<setw(15)<<number<<'\n';
}

list.h

#include "phone.h"
class list
{
	phone *head;
public:
	list(const char *last,const char *first,long num);
	~list();
	void insert(phone *p);
	phone *find_place(const char *last);
	phone *find(const char *last);
	phone *find_last_place();
	int del(const char *last);
	void print();
};

list.cpp

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

list::list(const char *last,const char *first,long num)
{
	head=new phone(last,first,num);
}
phone *list::find_last_place()
{
	phone *tmp,*prev;
	for(tmp=head,prev=head;tmp->next;prev=tmp,tmp=tmp->next);
	return(prev);
}
phone *list::find(const char *last)
{
	phone *tmp,*prev;
	for(tmp=head,prev=head;tmp!=NULL;prev=tmp,tmp->next)
		if(strcmp(last,tmp->last_name)==0)
			return(prev);
	return(prev);
}
phone *list::find_place(const char *last)
{
	phone *tmp,*prev;
	for(tmp=head,prev=head;tmp!=NULL;prev=tmp,tmp=tmp->next)
		if(strcmp(tmp->last_name,last)>=0)
			return(prev);
	return(prev);
}
void list::insert(phone *p)
{
	phone *tmp;
	//p->last_name the smallest
	if(strcmp(p->last_name,head->last_name)<0)
	{
		tmp=head;
		head=p;
		p->next=tmp;
		return;
	}
	//other cases
	tmp=find_place(p->last_name);
	p->next=tmp->next;
	tmp->next=p;
}
void list::print()
{
	phone *tmp;
	for(tmp=head;tmp!=NULL;tmp=tmp->next)
		tmp->print();
	cout<<"Total number od Objects are"<<head->n<<'\n';
}
int list::del(const char *last)
{
	phone *place,*tmp;
	//if the first object id being deleted
	if(!strcmp(last,head->last_name))
	{
		tmp=head;
		head=head->next;
		delete tmp;
		return(1);
	}

	place=find(last);
	tmp=place ->next;
	if(tmp==NULL||strcmp(tmp->last_name,last)!=0)
		return(0);
	else
	{
		place->next=place->next->next;
		delete tmp;
		return(1);
	}
}
list::~list()
{
	phone *tmp,*tmpn;
	for(tmp=head,tmpn=head->next;tmpn!=NULL;tmp=tmpn,tmpn=tmpn->next)
		delete tmp;
	delete tmp;
};

linkedlist.cpp

// linked list.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
#include "phone.h"
#include "list.h"
using namespace std;

int main()
{
	char last[15],first[15];
	long num;
	list *ll=new list("Lenon","Jenon",456641);
	phone *ph1=new phone("Haim","Moshe",345765),*ph2=new phone("Rabin","itzhak",467323),*phone_ptr;
	ll->insert(ph1);
	ll->insert(ph2);
	ll->print();
	ll->del("Haim");
	cout<<"AFTER DELETING\N";
	ll->print();
	cout<<"input last name first name phone number\n";
	do
	{
		cin>>last>>first>>num;
		phone_ptr=new phone(last,first,num);
		ll->insert(phone_ptr);
	}
	while(num);
	ll->print();
	delete ll;
	cin.get();
	return 0;
}

and visual studio writes me:

I think this book is too old and i will change the book to this:
