PseudocodeShorthand notation for

programming which uses a combination of informal programming structures and verbal descriptions of code.

What does this mean?• Pseudocoding requires you to know

how to read and write code so you can explain what a code is telling

the robot to do.

Purpose of Pseudocode

• The purpose is to create a reference that will allow you to

quickly fix any issues or alter lines of code.

• These quick references are referred to as Commands.
