but when output is written to the file, the current file pointer is disregarded. All output is
written at the end of the file, and the file pointer is repositioned at the end of the output.
When opening a binary file, the file position indicator may, in some cases, be positioned
beyond the last data written because of blank or null padding.
When opened, a stream is fully buffered only if it can be determined not to refer to an
interactive device. The error and end-of-file indicators for a stream are cleared.
