## Overview

This is a single-file C++ producer–consumer simulation. The producer and consumer maintain separate linked-list replicas and coordinate operations through a file-backed protocol channel; a file-backed Peterson implementation guards their critical sections. The excerpt shows initialization and these component responsibilities, but omits the program’s launch and some loop details, so those connections are not inferred.

Main entry points: [`practica2.cpp`](https://github.com/ddanrom05/productor-consumidor/blob/main/practica2.cpp) (Operation protocol)
