What are the three basic programming structures mentioned in the text?

• Sequences, selections, and loops

• Variables, functions, and arrays

• Classes, objects, and methods

• Inputs, outputs, and processes

What is a sequence in programming?

• A series of actions completed in a specific order

• A random set of actions performed simultaneously
