0x0C

0x0C is a hexadecimal literal representing the decimal value 12. The prefix 0x is used in many programming languages to denote hexadecimal notation, so 0x0C is commonly read as twelve in contexts such as C, C++, Java, and JavaScript.

In character encoding, 0x0C corresponds to the Form Feed control character, with the Unicode code point U+000C. This non-printable character originated as a device control used to advance to the next page on line printers and teletype machines. Today it is primarily of interest in text processing and data interpretation, where it may indicate a page break or be treated as a control signal in certain protocols.

In practical computing, 0x0C is often seen as a byte value in binary data, network protocols, and low-level programming. As a numeric constant, it equals the decimal number 12, and its binary representation is 00001100. Depending on the context, it may be used in flag masks, bitwise operations, or as a specific sentinel value.

Historically, form feed originated to control physical devices and pagemaking in early computing equipment. While its usage in everyday text has diminished, understanding 0x0C remains relevant for interpreting legacy data, debugging low-level code, and working with systems that rely on precise byte-level control.
