c++将二维数组写入json文档、释放动态二维数组内存

    //规划的路径写到.json文档中
    Json::Value root;
    root["type"]=Json::Value("south_global_plan_res");
    Json::Value data;
    data["deviceSerialNumber"]=Json::Value("JY12456789321654");
    data["planId"]=Json::Value("巡检计划ID");
    Json::Value array=data["siteList"];
    cout<<"path size!!"<position[1]*resolution+origin_x;
        double y=(502-Path[i]->position[0])*resolution+origin_y;
        array[i][0]=x;
        array[i][1]=y;
    }
    data["siteList"].append(array);
    root["data"]=Json::Value(data);
    Json::StyledWriter sw;
    ofstream file;
    file.open("path.json",ios::out);
    if(!file.is_open())
    {
        cout<<"error: can not find or creat !"<
