如何使用JsonCpp动态设置值？

#include <json/json.h>

Json::Value root;

root["name"] = "John";
root["age"] = 30;

Json::Value hobbies(Json::arrayValue);
hobbies.append("reading");
hobbies.append("swimming");
root["hobbies"] = hobbies;

std::string jsonString = root.toStyledString();

#include <iostream>
#include <json/json.h>

int main() {
    Json::Value root;
    root["name"] = "John";
    root["age"] = 30;

    Json::Value hobbies(Json::arrayValue);
    hobbies.append("reading");
    hobbies.append("swimming");
    root["hobbies"] = hobbies;

    std::string jsonString = root.toStyledString();
    std::cout << jsonString << std::endl;

    return 0;
}
