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: WebNov 14, 2024 · 1. 1. 1. The bitwise AND operator is a single ampersand: .
