Answer 1

I now StreamWriterBuilder method using for nice result !

Json::StreamWriterBuilder wbuilder;
wbuilder["indentation"] = "";
std::cout << "'" << Json::writeString(wbuilder, root) << "'" << std::endl;

Answer 2

FastWriter appends an additional line feed to each result. This can be really annoying.

Although FastWriter is now deprecated (and should be replaced with StreamWriterBuilder) you can omit this ending line by using omitEndingLineFeed()

Json::FastWriter writer;
writer.omitEndingLineFeed();
return writer.write(root);
