While-loops Drill

While loops are faster

While loops can handle unknown numbers of repetitions

While loops use less memory

While loops are easier to write

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

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

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

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
