## Question

Write down the guidelines to be followed to draw a flowchart.

## Short answer

Use standard symbols, a single Start and Stop, top‑to‑bottom flow with arrows, clear brief labels, no crossing lines, one operation per box, and verify with sample data.

## Answer

Follow these guidelines when drawing a flowchart:

- Use only the standard symbols (oval for start/stop, parallelogram for input/output, rectangle for process, diamond for decision).
- Every flowchart has exactly one **Start** and one **Stop**.
- Flow goes from top to bottom and left to right, shown with arrows; flow lines should not cross.
- Each symbol has a short, clear text; a decision symbol has one entry and two labelled exits (Yes/No).
- Do not put detailed code in the symbols; keep one operation in one box.
- Use connectors for a long chart and label them clearly.
- Keep the chart simple, neat and on one page where possible, and verify it with sample data.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. A flowchart has
   A. many Starts
   B. no Stop
   C. two Starts
   D. exactly one Start and one Stop
   Answer: D. Single entry and exit. (Key point: Start/Stop)

2. A decision symbol has
   A. one entry and two labelled exits
   B. two entries and one exit
   C. one entry and no exit
   D. three exits
   Answer: A. Yes/No branches. (Key point: Decision exits)

3. Flow lines should
   A. cross freely
   B. go top to bottom and left to right without crossing
   C. go bottom to top
   D. be omitted
   Answer: B. Keeps it neat. (Key point: Flow lines)
