#include <list>
#include <iostream>
#include <string>

using namespace std ;

class Apple;
class Basket;
typedef list<Apple> LISTApple;


class Apple
{
public:
      Apple(){second=0;first=0;};
      void setDATA(int, int);
    int getfirst();
      int getsecond();

private:
      int first;
      int second;

};
class Basket
{
public:
      void addNewApple(Apple);
      Apple getFirstApple();
      void showList();
private:

            LISTApple listApple;
};


void main()
{
      Apple newApple;
      Basket myReadyQ;

      newApple.setDATA(6, 3);
      myReadyQ.addNewApple(newApple);
      cout<<"second = "<<myReadyQ.getFirstApple().getsecond()<<endl;
      cout<<"first= "<<myReadyQ.getFirstApple().getfirst()<<endl;  // it works fine without to cout this statement
}

void Apple::setDATA(int First, int Second)
{
      first=First;
      second=Second;

}

int Apple::getfirst()
{
      return first;
}

int Apple::getsecond()
{
      return second;
}

void Basket::addNewApple(Apple newApple)
{

      listApple.push_front(newApple);            

}


Apple Basket::getFirstApple()
{
      LISTApple::iterator i;
      Apple selectedApple;

      i= listApple.begin();
      selectedApple=(*i);

      listApple.pop_back();
      return selectedApple;
}

void Basket::showList()
{
      LISTApple::iterator i;


      for (i = listApple.begin(); i != listApple.end(); ++i)
                cout <<"First = "<<(*i).getfirst()<<", second = "<<(*i).getsecond()<<endl;
}
