Flowcharts

Lesson 2: Using a Flowchart

To Know - Represent Algorithms in Flowcharts

To Be Able To - Use Flowcharts to Represent Code.

Describe the Purpose of Flowcharts when Showcasing Algorithms

What is a Flowchart?

A visual diagram that maps out a process, system, or computer algorithm step-by-step.

Flowcharts are use standarised symbols, which are used by multiple industries such as:

Business
Information Technologies
Manufacturing
Engineering
