When a file is closed, the operating system updates the information that tracks the end of the file, such as the file pointer position and the number of bytes written. This ensures that the file can be properly read and written to in the future. Opening a file using ios::eof or ios::app does not record this information, and the program ending may result in data not being properly saved to the file.
