What does a variable do in a flowchart?

In a flowchart, a variable represents a storage location for data that can change during the execution of a process. It is often depicted as a labeled box or symbol, indicating the value it holds at different points in the flow. Variables help track information, such as user inputs or intermediate calculations, allowing for dynamic decision-making and process flow. They play a crucial role in controlling the logic and operations within the flowchart.
