Reading values from a json file and storing them

[Lester702]

I just got started with jsoncpp in my game and I'm using it to store settings and to save the game and I've been able to write to a file, but I haven't been able to read a value from a json file

This is what I have come up with

std::ifstream file("settings.json");

    Json::Value jsonData;
    Json::CharReaderBuilder jsonReader;
    std::string errs;

    file >> jsonData;

    std::cout << jsonData << std::endl;

     const std::string dateString(jsonData["fpscounter"].asString());
     std::cout << dateString << std::endl;

The std::cout << jasonData << std::endl; line works fine and it prints the contents of the file to the console, but std::cout << dateString << std::endl; does not print anything

Maybe check if dateString is empty first and print an error msg?
What's the input file ?

Did you check if file is open ? std::fstream has "is_open()" function that return true if file is open and false if not.
