Question

Описать класс для работы с восьмеричным числом, хранящимся в виде строки символов. Реализовать конструкторы, свойства, методы и следующие операции:
- операции присваивания, реализующие значимую семантику;
- операции сравнения;
- преобразование в десятичное число;
- форматный вывод;
- доступ к заданной цифре числа по индексу.

English:

Describe a class for working with an octal number stored as a string of characters. Implement constructors, properties, methods, and the following operations:
- assignment operations that implement meaningful semantics;
- comparison operations;
- conversion to decimal;
- format output;
- access to a given digit of a number by index.

Answer 1

do you know octal numbers?
They only know digits from 0 to 7.

1740 is one
9147 is not an octal number.

Your task is to write a class for it.

Answer 2

how far is your prog?
Which points are open?

Answer 3

I do not understand what is required of me

Answer 4

Ok
Sometimes understanding comes with doing.

just begin with constructor that takes a string.

Answer 5

and after a method that compares two octal numbers....
step by step

Answer 6

almost
the constructor takes a string "12365" for example.

Answer 7

Yes

Answer 8

but what to write in the classroom? and just wrote the code to check (octal number entered, or not)

Answer 9

so, I need to make a constructor that will take an octal number. then which will take (or output?) a decimal string, and then write a method for comparing numbers, right?

Answer 10

ты знаешь восьмеричные числа?
Они знают только цифры от 0 до 7.

Ваша задача написать класс для него.
