Write a definition for function COSTLY() in C++ to read each record of a binary file GIFTS.DAT, find and display those items, which are priced more than 2000. Assume that the file GIFTS.DAT is created with the help of objects of class GIFTS, which is defined below

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;}
};

Solution

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();
}
