The answer to the following question is d. Run-time error. Can someone please explain this to me? I think that the last array element that is accessed is 5 which is 'F'. Doesn't the "i++" get evaluated before the comparison so that the output would be BCDEF? Don't we break out of the while loop before an access of arg[6] is attempted?
Thank you! These exams are very good. Very hard. They seem much harder than the JQ+ exams to me and the explanations are excellent.
