#include#include using json = nlohmann::json; int main() { json j = { {"name", "John"}, {"age", 30}, {"city", "New York"} }; if (j.is_object()) { std::cout << "The JSON value is an object." << std::endl; } else { std::cerr << "The JSON value is not an object." << std::endl; } return 0; }
#includeIn this example, we define a JSON string and parse it using the `rapidjson` library. We then check whether the parsed value is an object using the `IsObject` function. If it is, we print a message to the console. Package Library: The `nlohmann/json` library and the `rapidjson` library are common libraries used for JSON manipulation in C++.#include using namespace rapidjson; int main() { const char* json_str = "{\"name\": \"John\", \"age\": 30, \"city\": \"New York\"}"; Document d; d.Parse(json_str); if (d.IsObject()) { std::cout << "The JSON value is an object." << std::endl; } else { std::cerr << "The JSON value is not an object." << std::endl; } return 0; }
