Bitwise xor c example


Thus we get the bits inverted, for every bit 1 the result is bit 0 and conversely for every bit 0 we have a bit 1. This operation should not be confused with logical negation! 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 places the bits are shifted i. Here blank spaces are generated simultaneously on the left when the bits are shifted to the right. When performed on an unsigned type, the operation performed is a logical shift , causing the blanks to be filled by 0 s zeros.

When performed on a signed type, the result is technically undefined and compiler dependant, [5] however most compilers will perform an arithmetic shift , causing the blank to be filled with the sign bit of the left operand. It shifts each bit in its left-hand operand to the left by the number of positions indicated by the right-hand operand. It works opposite to that of right shift operator. Blank spaces generated are filled up by zeroes as above.

C provides a compound assignment operator for each binary arithmetic and bitwise operation i. Each of the compound bitwise assignment operators perform the appropriate binary operation and store the result in the left operand. Four of the bitwise operators have equivalent logical operators.

They are equivalent in that they have the same truth tables. However, logical operators treat each operand as having only one value, either true or false, rather than treating each bit of an operand as an independent value.

Logical operators consider zero false and any nonzero value true. Another difference is that logical operators perform short-circuit evaluation. This is because a logical operator must treat any nonzero value the same.
