5.4  Bit Manipulation

-- part contents for background part 4
----- text -----
In keeping with its heritage as a "low-level" (but extensible) language suited for writing operating systems, C provides numerous operators for bit manipulation.  Operands for these operators must be integral types.  For this purpose, integral values may be assigned using octal constants, which contain a leading zero:

    int    n = 077;     /* decimal value 63 */

Briefly, C's bit manipulation operators are:  bitwise negation (~); left shift (<<) and right shift (>>); bitwise AND (&), OR (|), and XOR (^); shorthand shift-assignment (<<= and >>=); shorthand AND-assignment (&=), OR-assignment (|=), and XOR-assignment        (^=).
