A flowchart is a graphical representation of an algorithm or a process, using various symbols to denote different types of actions or steps. Flowcharts are widely used in programming to plan and visualize the logic of a program before writing the actual code. They help in understanding, analyzing, and communicating the flow of a program.

Basic Symbols Used in Flowcharts

• Flow Line: Indicates the flow of logic by connecting symbols.

• Terminal (Start/Stop): Represents the start and end of a flowchart.

• Input/Output: Used for input and output operations.

• Processing: Represents arithmetic operations and data manipulations.

• Decision: Used for decision-making between two or more alternatives.

• On-page Connector: Used to join different flow lines on the same page.

• Off-page Connector: Used to connect flowchart portions on different pages.

• Predefined Process/Function: Represents a group of statements performing one processing task.
