Parsing C++ vector to JSON file

[cycbill]

Hi Forum,

I am trying to parse some C++ vector values into a JSON file in a following structure.
I am using the boost libraries such as <boost/property_tree/json_parser.hpp>.

However, I don't know how to save the vector data into the JSON in a format like: "Spot": [1.0, 2.0, 3.0, 4.0, 5.0].

Below is the data structure I want to achieve.

{
    "Crank-Nicolson" : {
        "Spot": [1.0, 2.0, 3.0, 4.0, 5.0],
        "PV": [11.0, 12.0, 13.0, 14.0, 15.0],
        "Delta": [21.0, 22.0, 23.0, 24.0, 25.0],
    },
    "Explicit Euler" : {
        "Spot": [1.0, 2.0, 3.0, 4.0, 5.0],
        "PV": [11.0, 12.0, 13.0, 14.0, 15.0],
        "Delta": [21.0, 22.0, 23.0, 24.0, 25.0],
    },
    "Implicit Euler" : {
        "Spot": [1.0, 2.0, 3.0, 4.0, 5.0],
        "PV": [11.0, 12.0, 13.0, 14.0, 15.0],
        "Delta": [21.0, 22.0, 23.0, 24.0, 25.0],
    }
}

GitHub - open-source-parsers/jsoncpp: A C++ library for interacting with JSON. might be more useful...

Tickled this a bit and got the attached main.cpp working just fine. I'd probably stick to an already created and optimized library like the one mentioned above. Beats sad looping

Thanks for the reply.
I did that too, but was think if there is a way to parse the vector data directly into a "[1,2,3,4]" format instead, which would reduce the file size without duplicated strings.
