I create a file like this:
i found i can only read the records , or position the file pointer toCode:... class Student { ... }; ifstream fin ( fname ); fin.write ( (char*)stud, sizeof ( Student ); //save student records ... ofstream fout ( fname ); ...
a specific record, however, i do not know how to delete a record
from a file, or modify of course .
thanks a lot for help !
