  1. A bitwise operation operates on one or more bit patterns or binary numerals at the level of their individual bits. It is a fast, primitive action directly supported by the central processing unit (CPU), and is used to manipulate values for comparisons and calculations.

    What does bitwise and do?
    The bitwise AND operator ( &) compares each bit of the first operand to the corresponding bit of the second operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0. Both operands to the bitwise AND operator must have integral types.

    Is a bitwise operator?
    In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher level arithmetic operations and directly supported by the processor.Most bitwise operations are presented as two-operand instructions where the result replaces one of the input ...

    In the explanations below, any indication of a bit's position is counted from the right (least significant) side, advancing left. For example, the binary value 0001 (decimal 1) has zeroes at every position but the first (i.e., the rightmost) one.

    There are two bitwise shift operators. They are
    • Right shift (>>)
    • Left shift (<<)
    The symbol of right shift operator is >>. For its operation, it requires two operands. It shifts each bit in its left operand to the right. The number following the operator decides the number of plac…

      • The description of C/C++ is incorrect insofar as unsigned integers (representing [0..(2^N)-1])act with the character of a "logical shift", whereas signed integers (representing [-2^(N-1)..0.. 2^(N-1)-1])are in some circumstances not defined and are left up to the implementation, regarding the presence ofupper order 1 bits subsequent to right-shift....
