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.

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 …

These are the bitwise operators, all supported in JavaScript: op1 & op2 -- The AND operator compares two bits and generates a result of 1 if both bits are 1; otherwise, it returns 0.

Aug 7, 2010 · Here is a quote from the book: The Bitwise AND Operator Bitwise ANDing is frequently used for masking operations. That is, this operator can be used easily to set specific …

Nov 17, 2009 · Bitwise operations in programming languages play a fundamental role when dealing with a lot of applications. Almost all low-level computing must be done using this kind …

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.

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 …

Well, Good question (duplicated though). Bitwise AND will affect its operators on the bit-level i.e. looping and doing logical AND operation on every bit. On the other hand, Logical AND will take …

What are some real world use cases of the following bitwise operators? AND XOR NOT OR Left/Right shift
