How to get JSON objects value using casablanca in C++ -


i new json. , m using codeplex (casablanca) reading json values.

below sample json string:

[{ "rollno": 2000, "name": "suhani","marks":{"grade":"c"}  },  {"rollno": 3000,"name": "ishu", "marks":{ "grade":"a"}  }]

the code access name & rollno, writing below code:

json::value jobj = json::value::parse(utility::conversions::to_string_t(resultbody));  (unsigned int = 0; < jobj.size(); i++) {     auto getval = jobj[i];      if (getval.at(u("name")).is_string()) {     auto xstr = getval.at(u("name")).as_string();     std::string wide = utility::conversions::to_utf8string(xstr);     std::string str(wide.begin(), wide.end());     string name = str; }  if (getval.at(u("rollno")).is_integer()) {     auto xstr = getval.at(u("rollno")).as_integer();     int rollno = xstr; } }

how value @ grade ?? when access marks of type object, not getting how access grade there. please respond.

marks still json object. you'll need access grade property. code snippet add following:

    (unsigned int = 0; < jobj.size(); i++) {         auto getval = jobj[i];         auto marks_object = getval.at(u("marks"));         auto grade_value = marks_object.at(u("grade")).as_string();

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
