Bitwise works on the binary level, so 0 on binary would seen as 0000_0000, and (in two's complemented) -1 is 1111_1111, this not 0 flips all the bits to 1s, thus alters 0 into -1. But in an …

In digital computer programming, a bitwise operation operates on one or more bit patterns or binary numerals at the level of their individual bits. It is a fast, primitive action directly …

The Bitwise operators are used to perform operations a bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are some times used to improve …

Aug 7, 2010 · The Bitwise AND Operator. Bitwise ANDing is frequently used for masking operations. That is, this operator can be used easily to set specific bits of a data item to 0. For …

Bitwise operators are useful for looping arrays which length is power of 2. As many people mentioned, bitwise operators are extremely useful and are used in Flags, Graphics, …

Jun 19, 2011 · The bitwise operators treat the bits inside an integer value as a tiny array of bits. Each of those bits is like a tiny bool value. When you use the bitwise exclusive or operator, …

Aug 24, 2008 · Using bitwise operations for bool helps save unnecessary branch prediction logic by the processor, resulting from a 'cmp' instruction brought in by logical operations. Replacing …

If you subtract one from that, it becomes: 0b1111, and using a bitwise and with that will effectively clear all upper bits in a way that gives you the analogical equivalent of n % 16. Similar thing …

Sep 18, 2008 · .NET's built-in flag enum operations are unfortunately quite limited. Most of the time users are left with figuring out the bitwise operation logic. In .NET 4, the method HasFlag …

I tried to understand how if condition work with bitwise operators. A way to check if a number is even or odd can be done by: #include <iostream> #include <string> using …
