Sequence, Selection and Iteration

Instructions carried out one after another in order is a...

• List

• Sequence

• Collection

• Series

Which is the definition of "sequence"?

• A set of instructions in a specific order

• Where instructions repeat

• Code where decisions are made

Which is the definition of "selection"?

• A set of instructions in a specific order

• Where instructions repeat

• Code where decisions are made

Which is the definition of "iteration"?

• A set of instructions in a specific order

• Where instructions repeat

• Code where decisions are made

Why is iteration important?

• It determines the order in which instructions are carried out

• It allows code to be simplified by removing duplicated steps

• It allows multiple paths through a program

Which statement is used to implement iteration?

• IF

• WHILE

Which statement is used to implement selection?

• IF

• WHILE

Which of the following contains an INCORRECT sequence when getting dressed to go out?

• Put on socks, put on shoes, put on coat

• Put on coat, put on shoes, put on socks

• Put on socks, put on coat, put on shoes

Why is selection important?

• Selection allows us to include more than one path through a solution

• Selection allows us to repeat steps in a solution

• Selection allows us make our solution more efficient

What type of algorithm can you see here?

• Sequence
• Selection
• Iteration
