While-loops Drill

What is the main advantage of using a while loop instead of a for loop in Karel programming?

• While loops are faster

• While loops can handle unknown numbers of repetitions

• While loops use less memory

• While loops are easier to write

In a while loop, when does the code inside the loop stop executing?

• After a fixed number of repetitions

• When the program reaches the end of the code

• When the condition becomes false

• When Karel reaches a wall

Which of the following best describes the purpose of the condition in a while loop?

• To count the number of repetitions

• To determine when to start the loop

• To decide whether to continue repeating the loop

• To define what actions Karel should take

In a Karel program to solve a maze, why might a while loop be more useful than a for loop?

• While loops are always faster in mazes

• The exact number of moves needed is unknown

• For loops can't be used with Karel

• Mazes always require exactly 100 moves

Which of the following is TRUE about while loops in Karel programming?

• They always need a counter variable

• They can only be used for movement commands

• They repeat a set of instructions based on a condition

• They must be used in combination with for loops
