Questions & Answers

Q: What is a flowchart?

A flowchart is a graphical representation of an algorithm using geometric symbols. It visually shows the steps and their order in a design or problem-solving process.

Q: How is a start/stop symbol represented in a flowchart?

The start/stop symbol is a rectangle with rounded edges. It can have fully rounded ends or just rounded edges. The text inside the symbol indicates whether it is for start or stop, determining if it has only output or input, respectively.

Q: What is the purpose of using rectangles in flowcharts?

Rectangles in flowcharts are used for calculations, mathematical formulas, and assignment instructions. They represent a step where some computation is performed.

Q: How are decisions or conditional statements represented in flowcharts?

Rhombuses are used for decision-making in flowcharts. They have one input and two outputs, with arrows marked as true and false indicating the different paths based on the condition.

Q: When are circles used in flowcharts?

Circles are used as connectors in flowcharts, typically when the algorithm representation spans multiple pages or sides. They establish a virtual connection and are marked with characters like "a," "$," or "#."

Summary & Key Takeaways

• Flowcharts are graphical representations of algorithms using geometric symbols.

• The start/stop symbol is a rounded rectangle with text indicating whether it is for input or output.

• Parallelograms represent input and output operations, with the specific action indicated by the text inside.

• Rectangles are used for calculations, mathematical formulas, and assignment instructions.

• Rhombuses denote decision or conditional statements, with arrows indicating true and false paths.

• Circles act as connectors for multi-page or multi-side flowcharts, with text indicating the connection.
