Source code in the rapira programming language

Фун Факт(n)
  f := 1
  для i от 1 до n
        f := f * i
  кц
  Возврат f
Кон Фун

Фун Факт(n)
  Если n = 1
    Возврат 1
  Иначе
    Возврат n * Факт(n - 1)
  Всё
Кон Фун

Проц Старт()
  n := ВводЦел('Введите число (n <= 12) :')
  печать 'n! = '
  печать Факт(n)
Кон проц

fun factorial(number)
  if number = 0 then
    return 1
  fi

  return number * factorial(number - 1)
end
