Запись в неинициализированную переменную, строго говоря, не UB. Но вообще в реальных кодовых базах чаще стараются все же инициализировать все переменные: int result {};


std::cout << "Guess a number from 0 to 9: ";
std::cin >> result;

return result;
}

int main() {
srand(unsigned(time(0)));

Приведение выполнится неявно автоматически. От приведения в стиле C особо ничего не изменится, разве что преобразование теперь перед глазами)


auto number = rand() % 10;

Если переменную можно сделать константой — так лучше и поступить

auto user_number = read_user_number();

while (user_number != number)
{
PRINT("Wrong!");
user_number = read_user_number();
}

PRINT("Correct!");
}
