C++
student s;
fin.read((char*)&s,sizeof(s));

where s is the object of the class.
and student is the mane of the class

What I have tried:

Basically nothing,

You already got an answer to your question but you should be careful when reading and writing class contents as they are. That won't work if your class contains dynamic objects (pointers to allocated objects).

Why not just try it, ans see what results you get?

Yes you can.
The compiler happily accetps
C++
fin.read((char*)&s,sizeof(student));
As you may easily verify.


The form
C++
fin.read((char*)&s,sizeof(s));
however is more robust (if you change the type of s it remains correct).
