Hey, I'm trying to write a class, called Country, which consists of a

- string, which is the name of the country

- vector<Country>, which is a vector of the neighboring countries.

At the moment my class looks like this

#ifndef COUNTRY_H
#define COUNTRY_H

#include <vector>
#include <string>

class Country{



std::string getName();


std::string name;

std::vector<Country> neighbours;


Now I want to be able to add neighbours to a country, but I don't want the function to be public.

To be more specific, I am going to create an Atlas class that will create, and store, the countries and read in the neighbours. So is there a way that I can add neighbours to a country from the atlas class, but not from anywhere else.

Any help would be greatly appreciated.

Have a look at the friend (http://www.codersource.net/cpp_tutorial_friend.html) modifier.

That looks like what I need, thanks. Seems like the best solution to me, but if anyone has any other ideas of how to do this then I would love to hear.

I dont think it will work , because , Country in here :

std::vector<Country> neighbours;

is an incomplete object.
it should be :

std::vector<Country*> neighbours;
