It says in answers that you cannot have something like
while (int k=5; k<7) ....

what about having while (k<7) - is that legal? I mean, if k was instantiated previous to while loop, then this expression should return true / false which is OK for while loop.

?

Thanks a mill!

Yes, while(k<7) is fine.

Thanks, Paul.

Hi,

If the while statement in the question is made to be (int k=5;k<7;) instead of (int k=5;k<7), it will be a bit more confusing. I for example somehow disregarded it's a while loop and thought it was an illegal for-loop (missing the last semicolon).

In the answer (int k=5;k<7;) is used and not (int k=5;k<7) as an example for an invalid while loop. I think this should be extended to the question itself to make it harder.

Good suggestion. But in a valid while loop, there is no semicolon. So from another perspective, the existing code might be more confusing to some because it looks like a valid while loop with initialization section.
