Создаем файл YourSkeet.cpp
И засовываем туда код
Создаем YourSkeet.h
Выводим в меню
Видим наш результат,
мы кароче перекурились и забыли кое что добавить
Создаем Json.cpp
Создаем Json.h
Вуалая, тема была взята с пастерс( не реклама)
Я сделал перевод бай Имфенкс.
И засовываем туда код

* The sequence of an #arrayValue will be automatically resized and initialized
* with #nullValue. resize() can be used to enlarge or truncate an #arrayValue.
*
* The get() methods can be used to obtain default value in the case the
* required element does not exist.
*
* It is possible to iterate over the list of a #objectValue values using
* the getMemberNames() method.
