У меня проблемы с тем, чтобы мое заявление о переключении делало то, что я хочу.Когда пользователь вводит «w» или «h», оператор должен вернуть его обратно, чтобы ввести новый вес или рост, но он этого не делает.Если кто-нибудь может указать мне, что я делаю неправильно, я был бы признателен.Спасибо
