Question

Write a function in C++ to add more new objects at the bottom of a binary file "STUDENT.dat", assuming the binary file is containing the objects of the following class :

class STU

{

int Rno;

char Sname[20];

public: void Enter()

{

cin>>Rno;gets(Sname);

}

void show()

{

count << Rno<<sname<<endl;

}

};

Answer 1

void Addrecord()

{

ofstream ofile;

ofile.open("STUDENT.dat", ios ::out);

STU S;

char ch='Y';

while (Ch=='Y' || Ch = = 'y')

{

S.Enter();

ofile.write (Char*) & S, sizeof(s));

cout << "more (Y/N)";

cin>>ch;

}

ofile.close();

}
