acess private members on diferent classes

So guys I'm making a computer game in university.. I'm having a trouble to make this working.. I have to make a game similar to Civilization, I've done some classes like this:

board - faction (vector) - cities - habitants
- artifacts (vector)

Basicaly my board includes some factions and artifacts.. My factions include some cities and habitants and then I've habitants outside the cities.. So I've done this..

That's my board:

Code:

class tabuleiro
{
	Consola c;          // predefined to acess console functions
	vector <faccao> f;     // factions
	vector <artefacto> a; // artifacts

	int posx, posy;
	int max_ox, max_oy;
	int fact_num;
	int dificuldade;
	string tipo;

public:
[....]

my factions

Code:

class faccao
{
	string nome;
	int ouro, comida, id, cor;

	vector <cidade> city;        // cities
	vector <habitante> hab;    // habitants
public:
[...]

city

Code:

class cidade
{
	string nome;
	int posx, posy, id, cor;

public:
	cidade(string nome2, int x, int y, int id2, int cor2); // constructor
	cidade(void);
	~cidade(void);
[...]

In the begining of the game we have to create a faction.. That's done, and then assossiate a city to it.

Code:

cidade cidad(f[i].get_nome(), posx+posx+2, posy+posy+2, i+1, 13); // Construtor
f[i].city.push_back(cidad); // The problem is here**

**Since I cannot use friend classes nor use public data how should I proceed?

Thanks in advance,
George

Use Member functions. I can't see any in your code.

Besides, your coding style is just awful.

Don't use (void) in C++. Just use empty brackets i.e. ()

Thanks kmdv and iMalc.. I know that my coding style isn't that great but I do have member functions liket GET and SET in all classes.. Thought the only one I'm not seing is how do I get vector city function (class faccao) so that the function would be seen as f[i].GET_city() (class tabuleiro)...

Thank you for your attention.

EDIT:

I do have declared in class faccao now

Code:

public:
	vector <cidade> city;		// ILEGAL!!! Alterar depois para private
	vector <habitante> hab;	// ILEGAL!!! Alterar depois para private

so I can use f[i].city[i].. But since this is public I cannot use that.

Right, you grant access to private members via accessors and mutators. You need to provide functions which add to the contained objects in your classes, like

Code:

city.addNewCity(const cidade &newCity)

Also, I would say that your contained classes should be plural to reflect that there may be more than one, so

Code:

class faccao
{
	string nome;
	int ouro, comida, id, cor;

	vector <cidade> cities;        // cities
	vector <habitante> habs;    // habitants
public:
        void addCity(const cidade &city) { cities.push_back(city); }
        cidade getCity(const string &name) { /* implement search via name */ }
[...]

Thanks rags_to_riches that's what I was missing.. It did the trick. Thanks man
