Guidelines for Developing Flowcharts
These are some points to keep in mind while developing a flowchart −
- Flowchart can have only one start and one stop symbol
- On-page connectors are referenced using numbers
- Off-page connectors are referenced using alphabets
- General flow of processes is top to bottom or left to right
- Arrows should not cross each other
Simple flowchart for adding two numbers:
- Start (Oval)
- Input Number 1 (Parallelogram)
- Input Number 2 (Parallelogram)
- Add Number 1 and Number 2 (Rectangle)
- Output the Result (Parallelogram)
- End (Oval)
