The kind specifier int suggests that the value that may be returned on the invoker (In cases like this the operate-time ecosystem) as a result of evaluating the principle functionality, can be an integer. The search term void like a parameter list suggests that this functionality requires no arguments.[b]

Programmers are superior at spotting homework questions; most of us have performed them ourselves. These inquiries are that you should exercise, so that you'll understand from the practical experience. It is actually OK to ask for hints, but not for total options.
