What is a state machine used for?
State Machines are used in applications where distinguishable states exist. Each state can lead to one or multiple states and can also end the process flow. A State Machine relies on user input or in-state calculation to determine which state to go to next.
Is every program a state machine?
4 Answers. If you want to be really pedantic, every computer program is a Finite State Machine, because even if you convert all matter in the entire universe into a computer, it will still only have finite memory, thus a finite amount of states, and a finite amount of transitions between those states.
How are state machines different from functional systems?
State machines are a method of modeling systems whose output depends on the entire history of their inputs, and not just on the most recent input. Compared to purely functional systems, in which the output is purely determined by the input, state machines have a performance that is determined by its history.

How is a state machine used in object oriented programming?
For example, in object-oriented programming, a state machine model may be used to model and test how an object moves from an inactive state to an active state readily accepting input and providing output.
Which is the first state of a state machine?
One state is marked as the initial state; this is where the execution of the machine starts. A state transition defines for which input a state is changed from one to another. Depending on the state machine type, states and/or transitions produce outputs.
