I'm stuck with jsoncpp. I would like to create an array like this:
"Cords": [{"x": 10, "y": 20}, {"x": 70, "y": 40}, {"x": 15, "y": 65}] I managed to do the regular stuff with jsoncpp (see below) but I am stuck in this case of making a JSON array.
Json::Value event; event["name"] = "Joe"; event["Direction"]["left"]["x"] = "1338"; event["Direction"]["right"]["x"] = "1337"; Edit:
I want to print it all within event.
I do not want to print cords separately.

You need to use the int overload of operator[] to define an array
Json::Value coord(int x, int y) { Json::Value result; result["x"] = x; result["y"] = y; return result; } void make_event(Json::Value & event) { Json::Value & coords = event["Cords"]; coords[0] = coord(10, 20); coords[1] = coord(70, 40); coords[2] = coord(15, 65); } May be something like this
Json::Value min; Json::Value event; event["x"] = 10; event["y"] = 20; min["Cords"] = event; // Output to see the result cout<<min.toStyledString() ncG1vNJzZmirpJawrLvVnqmfpJ%2Bse6S7zGiorp2jqbawutJoa3FrZ22Gen2OoaawZZSkeqp5zJqinmWRYre0u82cp6llkae%2FosU%3D
