The EOF is NOT a character or a byte in files, but only a special value to announce the end of file is reached, such as -1 (0xFFFFFFFF) returned from getc() function or 1 (True) returned from eof() function.

The end of a text file is often denoted by placing one or more special characters, known as an end-of-file marker, after the last line in a text file. Such markers were required under the CP/M and MS-DOS operating systems. On modern operating systems such as Windows or Linux, text files do not contain any special EOF character.

Old text file did have an end-of-file maker (in MS-DOS it was ‘\x1A’), and it is not the EOF itself, but only a sign to tell eof() function to return 1 in a text reading progress.

Text files can be considered as special case of binary files, where text is encoded in the ASCII format and split up into lines, along with end of line marker at the end of each line. Whereas, binary files do not. They are not split up into lines or records, but only binary data in bytes.

The end of line marker depends upon which operating system you are using:

• Macintosh: CR (carriage return, x’0D’, ‘\r’)
• Unix Based: LF (line feed, x’0A’, ‘\n’)
• Windows: CR + LF (x’0D0A’, ‘\r\n’)
