But in for loop we have an option of incrementing or decrementing outside the loop body. Also for loops have an option of initializing the variable. 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:
