WebIn C, the ternary conditional operator has higher precedence than assignment operators. Therefore, the expression e = a < d ? a++ : a = d, which is parsed in C++ as e = ((a < d) ? (a++) : (a = d)), will fail to compile in C due to grammatical or semantic constraints in C. See the corresponding C page for details. See also

WebBitwise Operators in C. The following table lists the Bitwise operators supported by C. Assume variable 'A' holds 60 and variable 'B' holds 13, then −. Binary AND Operator copies a bit to the result if it exists in both operands. Binary OR Operator copies a bit if it exists … WebBitwise operations are incredibly simple and thus usually faster than arithmetic operations. For example to get the green portion of an rgb value, the arithmetic approach is (rgb / 256) % 256. With bitwise operations you would do something as (rgb >> 8) & 0xFF. The latter is significantly faster and once you're used to it, its also easier.
