Getting null value after parsing the json file.

[Sandip7677]

After parsing data.json file using reader,getting null value. don't know what is wrong.
my code sample-

#include <iostream>
#include <fstream>
#include <string>
#include "json/json.h"
#include "json/value.h"
#include "json/reader.h"
using namespace std;
int main() {
  // read file
  ifstream file("data.json");
  // json reader
  Json::Reader reader;
  // this will contain complete JSON data
  Json::Value completeJsonData;
  // reader reads the data and stores it in completeJsonData
  reader.parse(file, completeJsonData);
  // complete JSON data
  cout << "Complete JSON data: " << endl <<completeJsonData << endl;
  // get the value associated with name key
  cout << "Name: " << completeJsonData["name"] << endl;
  // get the value associated with grade key
  cout << "Grade: " << completeJsonData["grade"] << endl;
  return 0;
}

After building I am gettng following output-

[build] Starting build

We'd have to see the contents of "data.json" to know if this is unexpected behavior.

Note that Json::Reader is deprecated and CharReader is now the supported parser.
