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 …

Jun 2, 2013 · Assume that the value of test is 1 or 0. Here I can implement the following if statement using bitwise operators as below.

The C89 Standard defined the behavior of left-shifting signed numbers based upon bit positions. If neither signed nor unsigned types have padding bits, the required behavior for unsigned …

The C ! operator is really just shorthand for != 0, so using it seems very close to cheating :). Here's my take just using bitwise operations, assuming a 32-bit two's complement machine …
