Answer Posted / abdur rab
When a file is opened with update mode ( '+' as the second
or third character in the mode argument), both input and
output may be performed on the associated stream. However,
writes cannot be followed by reads without an intervening
call to fflush or to a file positioning function (fseek,
fsetpos, or rewind), and reads cannot be followed by writes
without an intervening call to a file positioning function.
Since the file position is altered after read or write.
