WebFeb 16, 2024 · The bitwise inclusive OR operator ( ) compares each bit of its first operand to the corresponding bit of its second operand. If either bit is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0. Both operands to the operator must have integral types. The usual arithmetic conversions covered in ... WebMasking Using the Bitwise Operators. In the context of computer science, a mask, or bitmask, can be used to clear one or more bits to 0, set one or more bits to 1, or invert one or more bits as required. We’ve already seen an example of masking when we used the ^ (bitwise XOR) to invert bits 0 through 15 of myValueA.

WebIn the first loop, we are using the bitwise left shift operator (<<) to calculate the powers of 2. The left shift operator is equivalent to multiplying by 2. So, for example, 1 << 3 is the same as 1 * 2 * 2 * 2, which gives us 8. In the second loop, we are simply printing out the values in the array using cout. The output should look like this: WebC++ supports different types of bitwise operators that can perform operations on integers at bit-level.
