 Finite state machines (FSM) are present in almost every non trivial program.
 Guides on how to implement them are part of many programming

+sentence=A State Design Pattern for State Machines in C-Language.
 paragraph=CFSM follows a simplistic approach for the C-Language to implement maintainable state machines according to the STATE design pattern. This differentiates it from other solutions that often rely on complex macros to construct state handlers.
