I can't see a single advantage with it. Yasky and Ferruccio getting different answers to a sizeof for this approach should illustrate the problems with compatibility not just across compilers but across hardware. Remember, the macro substitution occurs in the preprocessor and so the generated code will reflect the fact that the values are considered constant by the compiler - i. It is, of course, possible and even appropriate to rewrite the equivalent of any of these macros with explicit mask values every time you need one, but why do it? The standards does not guarantee two's complement or arithmetic shift so it is better to use 1U. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. And when you want them for something other than bitmasks you get the automatic numbering. This code is broken.

  • In C, following 6 operators are bitwise operators (work at bit-level) 2) The bitwise XOR operator is the most useful operator from technical interview perspective. Find the Missing Number, swap two numbers without using a temporary. Bitwise Operators in C - Learn C programming in simple and easy steps Binary One's Complement Operator is unary and has the effect of 'flipping' bits. In the C programming language, operations can be performed on a bit level using bitwise This applies to bitwise operators as well, which means that even though they .

    Or gently promote the 1 by forcing a math operation that is as least as wide as the type of number. The C Programming Language 2nd ed. If you're doing a lot of bit twiddling you might want to use masks which will make the whole thing quicker.

    Your division on the other hand, will be translated to something around 10 ticks, or even as bad as up to ticks, depending on how poorly the specific architecture handles division.

    I can't see a single advantage with it. You'll probably be working with HEX representation, depending on the data structure in which you're packing bits. Bit operations now become a bit haha simpler: To set or clear a bit: mybits.

    C Bitwise Operators AND, OR, XOR, Complement and Shift Operations

    In the C programming languageoperations can be performed on a bit level using bitwise operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits known as bytes at a time.

    The fundamental genetic operators, mate selection, crossover and mutation, to take a bit from a chromosome and alter (i.e., flip) it with some predetermined n- dimensional unit cube, is a simple cycle C in Q, such that C has no chords in Q.

    Did you optimize for code-size? I am sure there are systems that don't use them and even the systems that do use them they are used judiciously but saying they are not used is just not correct because there are systems were they are used.

    Otherwise you have to resort to the bit-twiddling techniques described in previous posts. Bit fields are bad in so many ways, I could almost write a book about it. To address a common coding pitfall when attempting to form the mask: 1 is not always wide enough What problems happen when number is a wider type than 1?

    1. You could make it work, but it wouldn't necessarily be portable to a different processor, or to a different compiler or even to the next release of the same compiler. We sometimes fool ourselves that we've solved these issues with languages or defined runtimes but it really comes down to 'will it work on my machine?
