0x3C

0x3C is a hexadecimal literal representing the value 60 in decimal. In many programming languages, the 0x prefix denotes a base-16 number, so 0x3C conveys 60 when the number is parsed as hex. As an eight-bit quantity, 0x3C has a binary form of 00111100.

In ASCII, the decimal value 60 corresponds to the character '<', the less-than sign, and the Unicode code point U+003C represents the same character.

In practice, 0x3C appears in code as a byte value, in protocols or data representations; it is also the less-than symbol in text and is a special character in HTML and XML, requiring escaping as &lt; when displayed as text. The literal 0x3C is common in code samples and data dumps to indicate that specific byte.
