How would you describe a while loop?

• Check the condition; if it is true, then run a code block. Otherwise, run a different code block.

• Check whether the condition is true; if it is true, then keep repeating until the condition is false.

• Run a block of code and then check the condition; if the condition is true, then repeat the block of code.

Answer explanation

A `while` loop keeps repeating a block of code as long as the condition evaluates to a true value.

What kind of program structure is a while loop?

• infinite look

• iterative

• sequential

• selection

Why would we use a while loop instead of a for loop?

• we don't know how many times we want to run the loop

• we know how many times we want to run the loop

• It's a structure that is more efficient to code and execute

• it's best practicies
