Serialization in C++

Serialization in C++ is the process of converting complex data structures or objects into a format—such as a sequence of bytes—that can be stored or transmitted easily. This transformation allows data to be saved to a file or sent over a network, and later reconstructed back into its original form. Think of it as "flattening" an object into a storable or transmittable form, and then "rebuilding" it when needed. Serialization is essential for saving application states, sending data between systems, or ensuring data consistency across different environments.
