Basic JSON Serialization

JSON serialization is the process of converting C++ objects into JSON format. The nlohmann/json library makes this process straightforward. Here's a simple example of serializing a C++ object to JSON:

Basic JSON Deserialization

Deserialization is the process of converting JSON data back into C++ objects. The nlohmann/json library supports this with ease. Here is an example of deserializing JSON data into a C++ object:

Handling Complex JSON Structures

The nlohmann/json library can handle complex JSON structures such as nested objects and arrays. This is done by leveraging the library's powerful features, which allow for intuitive access and manipulation of JSON data. Here's an example:
