c1ass GIFTS
{
   int CODE; char ITEM[20]; f1oat PRICE;
pub1ic:
   void Procure()
  {
       cin>>CODE; gets (ITEM);cin>>PRICE;
  }
  void View()
  {
      cout<<CODE<<":"<<ITEM<<":"<<PRICE<<end1;

  f1oat GetPrice () {return PRICE;}
};

Answer 1

void COSTLY()
{
    GIFTS G;
    ifstream fin("GIFTS.DAT",ios::binary);
    while(fin.read((char *)&G,sizeof(G)))
    {
        if(G.GetPrice()>2000)
           G.View();
    }
    fin.close();
}
