Question

Is there any difference between exit-controlled loop structure and entry-controlled loop structure?

(a) Yes

(b) No

I had been asked this question during an interview.

I would like to ask this question from Looping topic in division Arduino Programming of Arduino

Answer 1

Right option is (a) Yes

Explanation: The minimum number of times an entry-controlled loop will run if the condition fails at first attempt is 0. However, the minimum number of times an exit-controlled loop will run if the condition fails at first attempt is 1. Here the difference is that in an entry-controlled loop, the condition is checked before entry into the loop structure, while in an exit-controlled loop, the condition is checked after the completion of the loop structure.
