a) Please post enough context. Keep in mind that news group postings
propagate independently through the net. As a consequence, a reply might
appear on a server before the question. In that case, the thread history
will not be available so you should not rely on that.

b) Here is the line in question:

student.write(reinterpret_cast<char *>(&studentInfo),sizeof(studentInfo));

If that line compiles, it just proves that student is not an array. Could it
be that student is some kind of stream?


Anyway, if you still have a problem with your code, please follow the
recommendations in FAQ clause [5.8].
