    json array = {1, 2, 3, 4, 5};

:memo: cleanup after #650 As <iostream> is not included in json.hpp any more, all code examples need to include <iostream> now. 2017-07-09 17:51:38 +08:00			`#include <iostream>`
:memo: fixed examples for Wandbox As I learned in https://github.com/melpon/wandbox/issues/209, this library is already installed at Wandbox, so we need to adjust the examples to use `#include "json.hpp"` insteas of `#include <json.hpp>`. 2017-04-22 04:07:07 +08:00			`#include "json.hpp"`
