2.9 Bitwise Operators

• Six operators for bit manipulation:

• The operators can only be applied to integral operands - int, char, short and long (signed or unsigned)
• bitwise AND operator is often used to mask off some set of bits
• bitwise inclusive OR operator is used to turn bits on
• bitwise exclusive OR operator set a one in each bit position where its operands have different bits, and zero where they are the same
• Shift operator shift the bit position of operand and fill vacated bits with zero
• Unary operator yields the one's complement of an integer (convert each 1-bit into 0-bit and vice versa)
