A flowchart is a visual diagram used to describe an algorithm. It enables you to describe the key steps of your algorithms and highlights when the user will be required to input data, when the computer will output/display information to the end-user, when a decision block (Selection / IF Statement) or a loop (Iteration) is used.
A flowchart uses specific shapes including:
- Oval shapes to represent the START and END of an algorithm,
- Parallelogram shapes to represent interactions with the end-user (INPUT and OUTPUT),
- Rectangle shapes to represent a process or a calculation,
- Diamond shapes to represent an IF Statement (Selection) or a LOOP (iteration).
