Question

Write a function in C++ to search and display details. of all trains, whose destination is “Delhi” from a binary file “TRAIN.DAT”. Assuming the binary file is containing the objects of the following class.

class TRAIN

{ int Tno;     // Train Number

char From[20];   // Train Starting Point

char To[20]; // Train Destination

public:

 char* GetFrom (){return From;}

 char* GetTo (){return To;}

 void Input () {cin>>Tno;gets(From);gets(To);}

 void Show () {cout<<Tno<<:<<From<<:<<To<<endl;}

};

Answer 1

void Read ( )

{ TRAIN T;

ifstream fin;

fin. open (TRAIN.DAT, ios::binary);

while(fin.read((char*)&T, sizeof(T)))

{

if(strcmp(T.GetTo() ,Delhi)==O)

T.Show() ;

}

fin.close(); //Ignore

}
