Answer 1

The mistake is indeed hard to spot. I handtraced it to line 24 though.
Go through your function with 100 as the argument. You'll notice that in line 24, you indirectly divide by 0 - remainder needs division - and thus the program stops working.
You should make an extra else-if case that covers 0.

Answer 2

Interesting
I'm trying for a while
I found out something
it's if who is disturbing and if covers function

Answer 3

line 49 is added to check whether the problem is with for loop or with the function isGapful, thus the output looks weird.

Answer 4

Yep if we start from 101 it works weirdly but works
edit: because of other cout i

Answer 5

Thanks for finding out that the problem occur at line 24.
I should use n2=n2/10 at line 11.
