APCSP - Algorithms: Sequencing, Selection, and Iteration

When we execute an algorithm, we always run each statement in order. This is formally referred to as ______________.

• Sequencing

• Selection

• Iteration

• The Goose Lord's Decree

Algorithms often need to check some condition (a boolean expression) and do different things depending on whether it is true or false. This is known as __________________.

• Sequencing

• Selection

• Iteration

• Bees?

Sometimes a section of an algorithm repeats, either a fixed number of times or until a certain condition is met. This is known as ___________________.

• Sequencing

• Selection

• Iteration

• Titration

I made this program to simulate rolling a 6-sided die. I win if the number rolled is 1, 5, or 6, and you win if it's 2, 3, or 4. Which is a correct missing condition?

• roll = 1 AND roll > 4

• roll < 2 OR roll >= 5

• roll > 2 AND roll <= 4

• roll > 1 OR roll < 5

How many times will "hi" be displayed by this code?

• 5 times

• 4 times

• 3 times

• 2 times
