• After the first execution

• At the end of the loop

• At the beginning of the loop

What type of problems does a WHILE loop typically apply to?

• Constant values

• Fixed iterations

• Unknown number of repetitions

• Known number of repetitions

What is the purpose of the control variable in a FOR loop?

• To hold user input

• To store the final result
