Help me to find mistakes

Question

Hi! I've recently started learning C++ and now I have problems with recursion. The results of two functions have to match, but they don't. The first one is iteration, the second is recursion. I can't get what's wrong. Please, help me with it.

Answer 1

The return statement in the 'iter' function should be outside the for loop.

Answer 2

Ulisses Cruz, thank you, I didn't know that. But the results, if I enter, for example, 2, still don't match.
