#includeIn the above example, we create a JSON object `root` that contains two fields, `name` and `age`. We then create a file stream and write the JSON object to a file named `out.json`. The Cpp JSON Value library is part of the larger Cpp JSON library, which provides a complete set of tools for working with JSON data structures in C++. The library is available for download on GitHub, and it is licensed under the MIT license.#include int main() { Json::Value root; root["name"] = "John"; root["age"] = 30; std::ofstream file("out.json"); file << root; file.close(); return 0; }
