Raptor Flowchart Best Practices


In this tutorial, we will learn some Raptor flowchart best practices to create more readable, understandable flowcharts. If you use Raptor in academic work, you can improve grades following these steps.

Naming conventions

Follow standard naming conventions for variables, constants, procedure names etc. CamelCase is standard way to name the variables.

Choose meaning full names for the variables and be descriptive. Meaningful and descriptive variables names enhance the readability of the flowchart.

‘rectangleArea’ is more meaningful instead of ‘a’ to denote area of the rectangle.

Differentiate constants and variables in your flowcharts. Use uppercase letters for constants. Constants once assigned a value don’t change in the flowchart.

User prompts

When we prompt the user for input in the flowcharts, add details to the prompts and be polite and graceful. Remember that the instructor will run your flowchart before giving  you the grades or marks 🙂


Add appropriate spacing to increase readability in Assignment symbols, Output statements. Adding spaces adds ‘look and feel’ and increases readability of the flowchart and makes it less clumsy.


Add program header comments to the flowchart with your details like name, data, class, roll number, program description etc.
