  5. The code will not compile because of line 5.
  6. The code contains an infinite loop and does not terminate.




Answer



F.

Note

The optional update statement of the for loop is missing.

The expression (i = i++;) inside the loop increments i but then assigns i the old value. i stays in value 0 for ever.

The loop will repeat infinitely.
