Question 57

In `a if condition else b`, which result expressions are evaluated?

  1. Both `a` and `b` before the condition
  2. Neither result expression; it returns the condition
  3. Always `a`, because the `else` part is optional
  4. Only `a` or `b`, whichever the condition selectsCorrect answer
