Bitwise Operations We have seen arithmetic and logical integer operations. C also supports bitwise operations. These operations correspond to circuit elements. They are often related to, …

Suppose we want to divide an integer N by a power of 2, say 2K. Then, mathematically, the quotient is just N shifted K bits to the right and the remainder is just the right-most K bits of N. …

Depending on your application, bitwise operators can be essential for reaching peak performance or keeping your data footprint small. C provides the following bitwise operators. All but the …

Bitwise Operators. C++ provides bitwise operators, which provide these operations: & y | y ^ y ~x << y >> y

The | (vertical bar) operator performs a bitwise OR on two integers. Each bit in the result is 1 if either of the corresponding bits in the two input operands is 1.
