#includeIn this example, a JSON string `"{ "myNumber": 42 }"` is parsed using the `Json::Reader` class, which creates a `Json::Value` object called `root`. The `asInt` method is then called on the `root["myNumber"]` object to extract the integer value 42, which is stored in the `myNumber` variable. The package library used in this example is the `jsoncpp` library, which provides a C++ interface for working with JSON data.#include "json/json.h" int main() { std::string jsonStr = "{ \"myNumber\": 42 }"; Json::Value root; Json::Reader reader; bool parsingSuccessful = reader.parse(jsonStr, root); if (!parsingSuccessful) { std::cout << "Failed to parse JSON" << std::endl; return 1; } int myNumber = root["myNumber"].asInt(); std::cout << "My number is " << myNumber << std::endl; return 0; }
