What are the functions of the JSON library in C++?

The JSON library in C++ provides the following features:

1. Parsing and generating JSON data: The JSON library allows you to parse JSON data from a string or input stream, and convert C++ objects to a JSON-formatted string or output stream.

Accessing and modifying JSON data: The JSON library offers a range of APIs to access and modify the key-value pairs, array elements, and nested objects within a JSON object.

3. Supports a variety of data types: The JSON library supports fundamental data types, such as strings, integers, floating point numbers, boolean values, and null values, as well as complex data types like arrays and nested objects.

4. Working with JSON objects and arrays: The JSON library offers methods for creating, accessing, and modifying JSON objects and arrays.

Validate and verify JSON data: The JSON library enables you to validate the validity of JSON data and provides methods to check data types, the existence of keys, and more.

Serialization and deserialization: The JSON library can convert C++ objects into JSON formatted strings and can also convert JSON data back into C++ objects.

7. Supports streaming operations: The JSON library offers a streaming API that makes it more efficient and memory-friendly to handle large JSON datasets.

Some common C++ libraries for working with JSON include:

RapidJSON is a high-performance and feature-rich JSON library that supports parsing, generating, accessing, and modifying JSON data.

nlohmann/json is a user-friendly JSON library that offers a clean API for parsing, generating, accessing, and modifying JSON data.

JsonCpp is a cross-platform library for working with JSON data, allowing for parsing, generating, accessing, and modifying JSON data.

Poco JSON is a module within the Poco project that offers functionality for parsing, generating, accessing, and modifying JSON data.

Boost.PropertyTree is a versatile configuration library that can also be used for handling JSON data.
