Best State Machine Libraries for C++

Are you looking for the best state machine libraries for C++? Look no further! In this article, we will explore some of the top state machine libraries available for C++ developers.

But first, let's talk about what a state machine is and why it's important. A state machine is a mathematical model used to describe the behavior of a system. It consists of a set of states, transitions between those states, and actions that occur when a transition is made. State machines are used in a wide range of applications, from embedded systems to video games.

Now, let's dive into the best state machine libraries for C++:

Boost.Statechart

Boost.Statechart is a powerful and flexible state machine library for C++.
