Solution

The output of the given code snippet will be:

4 10 18

Here's the step-by-step explanation:

  1. Initialize a to 1 and b to 0.
  2. Enter the while loop because a (1) is less than or equal to 3.
  3. Increment a by 1, making a now 2.
  4. Add a * 2 (which is 4) to b, making b now 4.
  5. Print b, which is 4.
  6. Since a (2) is still less than or equal to 3, repeat the loop.
  7. Increment a by 1, making a now 3.
  8. Add a * 2 (which is 6) to b (which is 4), making b now 10.
  9. Print b, which is 10.
  10. Since a (3) is still less than or equal to 3, repeat the loop.
  11. Increment a by 1, making a now 4.
  12. Add a * 2 (which is 8) to b (which is 10), making b now 18.
  13. Print b, which is 18.
  14. Now a (4) is greater than 3, so the loop ends.
