Return - why here?

Question about the task

Under discussion

Hi! Why do we need the "return" command here? We want to have euro to usd exchange - that was the task, so we do not need to return from usd to euro.

If the method is not void, then you need to return something. And if the method were void, it would be a useless method. The method would not have any side effects and the whole call would be useless.
