JSONCPP Writing to files

Question

JSONCPP has a writer, but all it seems to do is get info from the parser and then output it into a string or a stream. How do I make it alter or create new objects, arrays, values, strings, et cetera and write them into the file?

Answer 1

#include<json/writer.h> 

Code:

    Json::Value event;        Json::Value vec(Json::arrayValue);     vec.append(Json::Value(1));     vec.append(Json::Value(2));     vec.append(Json::Value(3));      event["competitors"]["home"]["name"] = "Liverpool";     event["competitors"]["away"]["code"] = 89223;     event["competitors"]["away"]["name"] = "Aston Villa";     event["competitors"]["away"]["code"]=vec;      std::cout << event << std::endl; 

Output:

{         "competitors" :          {                 "away" :                  {                         "code" : [ 1, 2, 3 ],                         "name" : "Aston Villa"                 },                 "home" :                  {                         "name" : "Liverpool"                 }         } }
