帮助JSON文件 [英] Help with JSON files

问题描述

实际上我想在C ++程序中编写和读取JSON文件中的数据。我已经处理过文本文件并知道如何实现文件I / O.But JSON就是我刚才听到的。这是一个简单的程序，涉及阅读，编写和修改记录。这些记录是从JSON文件中读取和写入的。



我通过互联网搜索并发现我需要一个解析器库。所以我下载了JSONcpp。但是没有关于如何使用它来编码和解码JSON文本的文档。最欢迎任何帮助或有用的链接！

Actually I want to write and read data from JSON files in a C++ program.I have worked on text files and know how to implement file I/O for the same.But JSON is what I have just heard of.This is a simple program that involves reading,writing and modifying records. The records are read from and write onto JSON files.

I searched over the internet and found I need a parser library for the same.So I downloaded JSONcpp. But there's no documentation regarding how to use it to encode and decode JSON text.Any help or helpful links are most welcomed!

项目页面包含如何例子。

The project page includes a "how to" example.

Json::Value root;   // will contains the root value after parsing.
Json::Reader reader;
bool parsingSuccessful = reader.parse( config_doc, root );
if ( !parsingSuccessful )
