Flowchart
A flowchart is a visual diagram that represents a process, workflow, or algorithm using standardized symbols (e.g., rectangles for steps, diamonds for decisions, arrows for flow direction). It is used to document, analyze, design, or communicate complex procedures in a clear, step-by-step manner. Flowcharts are widely applied in software development, business process modeling, and system design to illustrate logic and decision paths.
Developers should learn flowcharts to effectively plan and document algorithms, system workflows, or user interactions before coding, which helps in debugging, team collaboration, and requirement analysis. They are particularly useful in software engineering for designing program logic, mapping data flows in systems, and creating visual specifications for projects like business process automation or educational tutorials.
