For example, when shifting a 32 bit unsigned integer, a shift amount of 32 or higher would be undefined. Example: If the variable ch contains the bit pattern 11100101, then ch >> 1 will produce the result 01110010, and ch >> 2 will produce 00111001. Here blank spaces are generated simultaneously on the left when the bits are shifted to the right.
Thus, if both bits in the compared position are 1, the bit in the resulting binary representation is 1 (1 × 1 = 1); otherwise, the result is 0 (1 × 0 = 0 and 0 × 0 = 0). For example: 0101 (decimal 5) AND 0011 (decimal 3) = 0001 (decimal 1) The operation may be used to determine whether a particular bit is set (1) or cleared (0). For example ...
Various implementations of C and C++ reserve 8, 9, 16, 32, or 36 bits for the storage of a byte. [67] [68] [g] In addition, the C and C++ standards require that there be no gaps between two bytes. This means every bit in memory is part of a byte. [69] Java's primitive data type byte is defined as eight bits. It is a signed data type, holding ...
Historically, a byte was the number of bits used to encode a character of text in the computer, which depended on computer hardware architecture, but today it almost always means eight bits – that is, an octet. An 8-bit byte can represent 256 (2 8) distinct values, such as non-negative integers from 0 to 255, or signed integers from −128 to ...
The symbol for the binary digit is either "bit", per the IEC 80000-13:2008 standard, or the lowercase character "b", per the IEEE 1541-2002 standard. Use of the latter may create confusion with the capital "B" which is the international standard symbol for the byte.
The term byte string usually indicates a general-purpose string of bytes, rather than strings of only (readable) characters, strings of bits, or such. Byte strings often imply that bytes can take any value and any data can be stored as-is, meaning that there should be no value interpreted as a termination value.
CHAR_BIT – size of the char type in bits, commonly referred to as the size of a byte (at least 8 bits) SCHAR_MIN , SHRT_MIN , INT_MIN , LONG_MIN , LLONG_MIN (C99) – minimum possible value of signed integer types: signed char, signed short, signed int, signed long, signed long long
