What control character signals the end of the input file?
Answers
Explanation:
In telecommunication, an End-of-Transmission character (EOT) is a transmission control character. Its intended use is to indicate the conclusion of a transmission that may have included one or more texts and any associated message headings.[1]
An EOT is often used to initiate other functions, such as releasing circuits, disconnecting terminals, or placing receive terminals in a standby condition.[1] Its most common use today is to cause a Unix terminal driver to signal end of file and thus exit programs that are awaiting input.
In ASCII and Unicode, the character is encoded at U+0004 <control-0004>. It can be referred to as Ctrl+D, ^D in caret notation. Unicode provides the character U+2404 ␄ SYMBOL FOR END OF TRANSMISSION (HTML ␄) for when EOT needs to be displayed graphically.[2] In addition, U+2301 ⌁ ELECTRIC ARROW can also be used as a graphic representation of EOT; it is defined in Unicode as "symbol for End of Transmission".[3]
