What are the Differences between a State Machine Diagram and a Flowchart?

What is a Flowchart?

An algorithm is like a set of clear instructions to solve a problem, and a flowchart is a picture that shows those instructions.

When we’re writing computer programs, a flowchart helps us map out the steps of the algorithm to solve the problem.
Non programmers use Flow charts to model workflows.
We can call a flowchart a primitive version of an activity diagram.
Business processes where decision making is involved is expressed using a flow chart.

Example:

A manufacturer uses a flow chart to explain and illustrate how a particular product is manufactured.

State Machine Diagram VS Flow Chart?

State Machine Diagram	Flow Chart
An State Machine Diagram is associated with the UML(Unified Modelling Language)	A Flow Chart is associated with the programming.
The basic purpose of a state machine diagram is to portray various changes in state of the class and not the processes or commands causing the changes.	A flowchart on the other hand portrays the processes or commands that on execution change the state of class or an object of the class.
Primarily used for systems, emphasizing their states and transitions.	Often used for processes, procedures, or algorithms involving actions and decisions.

State Machine Diagrams | Unified Modeling Language (UML)3. How to draw a State Machine diagram in UML?

A State Machine Diagram is used to represent the condition of the system or part of the system at finite instances of time. It’s a behavioral diagram and it represents the behavior using finite state transitions.
