Thread: Problems defining classes

So,if I understood you correctly,since a owner can have multiple vehicles we should have a pointer in both classes?Something like this?:

Code:

class owner
{
private:

  string name;
  string address;
  long id;
  long phone;

public:

  owner(string o_name,string o_address, long o_id,long o_phone);//constructor
  void getname (void) const;
  string setname(string o_name);
  //etc,other gets and sets 
}

class vehicle
 {
private:

  string model;
  string brand;
  string license;
  long nr_oldowners;

public:

  vehicle(string v_model,string v_brand,string v_license,long v_nr_oldowner)
  void getlicense (void) const;
  string setlicensestring o_name);
  //etc,other gets and sets 
}

class autoreg
{

private:

  vehicle *v;
  owner  *o;

public:

     insert_v(string v_model,string v_brand,string v_license,long v_nr_oldowner);//is this okay??

     insert_o(string v_model,string v_brand,string v_license,long_nr_oldowner,string o_name,string o_address, long o_id,long o_phone););//is this okay??

     erase_o(string o_name,string o_address, long o_id,long o_phone););//is this okay??

     erase_v(string v_model,string v_brand,string v_license,long v_nr_oldowner););//is this okay??

     update(string v_model,string v_brand,string v_license,long_nr_oldowner,string o_name,string o_address, long o_id,long o_phone););//is this okay??
   
}

You mean the

Code:

insert_v(string v_model,string v_brand,string v_license,long v_nr_oldowner)

method,making it constant?
