How to iterate?

[ghost]

Hi, i couldn't figure out how to iterate over some simple json data like this:

string sJson=
			"{"
				"\"data\": ["
					"{"
						"\"id\": \"1000\""
					"},"
					"{"
						"\"id\": \"1001\""
					"},"
					"{"
						"\"id\": \"1002\""
					"}"
				"]"
			"}";

Please could you provide an example how to print all the ids?
In addition not being able to forward declare your stuff is a big show stopper.

Ok, i had to use

json j = json::parse(sJson);

instead of

json j = sJson;

The latter seems to add the sJson's text as a value to the json document.
After all this constructor doesn't make much sense for me...

You could also use a user-defined string literal:

json j = R"(
{
  "key": "value",
  "another key": [1,2,3]
}
)"_json;
