0x4B

0x4B is a hexadecimal numeral written with the 0x prefix, representing the value 75 in decimal. The 0x prefix is a common convention in many programming languages, including C, C++, Java, JavaScript, and Python, to indicate that the digits following are in base 16.

In ASCII and Unicode, 0x4B corresponds to the capital letter K: the ASCII code 75 decimal is 0x4B in hex, and the Unicode code point U+004B also represents the character 'K'. This means that in text encodings that use ASCII or Unicode, the byte 0x4B encodes the letter K.

As a fixed numeric value, 0x4B can be used in code for a variety of purposes, such as constants, bitwise operations, or masks. It may also appear in contexts like memory addresses or as part of larger hexadecimal literals that encode color values or other data. In most programming languages, 0x4B is automatically interpreted as the integer 75.

Examples of its use include: in C or C++, int a = 0x4B; which assigns 75 to a; in Python, 0x4B evaluates to 75; in JavaScript, const a = 0x4B also yields 75. While 0x4B itself is simply a numeric literal, its interpretation depends on the surrounding context and the language in use.
