Binary File in C++ :- Creation of File, Writing Data into File, Searching for Required Data from File, Appending Data to a File, Insertion of Data in Sorted File, Deletion of Data from File, Modification of Data in a File

Find the output of the following C++ code considering that the binary file MEMBER.DAT exists on the hard disk with records of 100 members :

c1ass MEMBER
{
  int Mno; char Name[20];
pub1ic:
  void In();void Out();
};

void main()
{
  fstream MF;
  MF.open("MEMBER. DAT" , ios::binary|ios::in);,

  MEMBER M;
  MF.read((char*)&M, sizeof(M));
  MF. read( (char*) &M, sizeof (M));
  MF. read ((char*) &M, si:zeof (M));
  int POSITION= MF. te11g 0 / sizeof (M);
  cout<<"PRESENT RECORD:"<<POSITION<<end1;
  MF.c1ose();
}

Find the output of the following C++ code considering that the binary file CLIENTS.DAT exists on the hard disk with a data of 200 clients:

class CLIENTS
{
    int CCode; char CName[20];
public:
    void REGISTER(); void DISPLAY();
};

void main()
{
    £stream File;
    File.open("CLIENTS.DAT", ios::binary|ios::in);
    CLIENTS C;
    File.seekg(6*sizeof(C));
    File.read((char*)&C, sizeof(C));
    cout<<"Client Number: "<<File.tellg()/sizeof(C) + 1;
    File.seekg(0 , ios :: end) ;
    cout<<"of"<<File.tellg(}/sizeof(C)<<endl;
    File.close();
}

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;}
};

Write a definition for function COUNTPICS() in C++ to read each object of a binary file PHOTOS.DAT, find and display the total number of PHOTOS of type PORTRAIT. Assume that the file PHOTOS.DAT is created with the help of objects of class PHOTOS, which is defined below :

class PHOTOS
{
   int PCODE ;
   char PTYPE[20]; //Photo Type as "PORTRAIT" ,"NATURE"
public:
   void ENTER()
   {
       cin>>PCODE;gets(PTYPE);
   }
   void SHOWCASE()
   {
       cout<<PCODE<<":" <<PTYPE<<endl;
   }
   char *GETPTYPE(){return PTYPE;}
};
