Working
This table shows the changes in the value of i as the for loop iterates:
| i | Remarks |
|---|---|
| -1 | Initial value |
| 0 | 1st Iteration — i is -1, ++i makes it 0 |
| 2 | 2nd Iteration — i becomes 1, ++i makes it 2 |
| 4 | 3rd Iteration — i becomes 3, ++i makes it 4 |
| 6 | 4th Iteration — i becomes 5, ++i makes it 6 |
| 8 | 5th Iteration — i becomes 7, ++i makes it 8 |
| 10 | 6th Iteration — i becomes 9, ++i makes it 10 |
| 11 | Once i becomes 11, condition is false and loop stops iterating. |
