• C A decision

• D Step by step instructions used to solve a problem

What are the three algorithm constructions?

• A Input, Output, Process

• B Sequence, Selection, Repeat

• C Input/Output, Decision, Repeat

• D Loop, Input/Output, Process

What is the difference between a flowchart and a pseudocode?

• A A flowchart is a diagram while the pseudocode is written in a programming language (e.g. Pascal or Java)

• B A flowchart is textual but the pseudocode is a diagram
