0x71

0x71 is the hexadecimal notation for the integer 113. In binary it is 01110001. Hexadecimal notation is commonly used in computing because it maps neatly to four-bit groups, making it convenient to express bytes and bit patterns.

In character encoding, 0x71 corresponds to the lowercase Latin letter q in ASCII, and the same code point appears in Unicode as U+0071. This means that in typical ASCII-compatible encodings, the byte value 0x71 represents the character q.

In programming, 0x71 is encountered as a byte value within data streams, buffers, or as part of numeric literals. Many languages allow hexadecimal literals to be written with a 0x prefix, so 0x71 would be interpreted as the decimal value 113. It can appear in bitwise operations, masks, or when constructing larger values from bytes (for example, as the least significant byte of a 16-bit value).

While 0x71 has no inherent special meaning beyond its numeric value, its role as the code for the character q in ASCII and its presence as a common byte value in data make it a frequently referenced example in introductory discussions of hexadecimal notation and encoding.
