JSONCPP Writing to files

Question

JSONCPP has a writer, but all it seems to do is get info from the parser and then output it into a string or a stream. How do I make it alter or create new objects, arrays,

Answer 1

First, you have to create the desired JSON::Value. You should look at all the constructors (first). To create the necessary hierarchies, see append and the operator[] overloads; there are overloads for both array indices and string keys for objects.

One way to write the JSON value back out is using StyledStreamWriter::write and ofstream.

See cegprakash's answer for how to write it.
