FAQ
Frequently Asked Questions
In technical writing, the hyphenated form 'end-of-file' is often used attributively (e.g., end-of-file marker), while 'end of file' is used predicatively (e.g., we reached the end of file). The abbreviation EOF is common for both.
It would sound highly technical and out of place. In everyday contexts, you would simply say 'the end of the document' or 'the end of the list'.
It depends on the programming language and context. Typically, a read operation fails or returns a special value (like NULL or -1), signalling that no more data is available.
Not exactly. While some older systems (like MS-DOS) used a specific Ctrl+Z or Ctrl+D character to *indicate* EOF, EOF itself is a logical condition or a special value returned by input functions.
