This is given below −. cout << "Enter first number:"<> num1; cout << "Enter second number:"<> num2; After that, addition is carried out using a while loop. It involves using the bitwise AND ... 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: ioo all mesh and fabric mesh combo
