What is the consequence of using 'turnLeft()' multiple times in a row?

• A. Karel spins in circles
• B. Karel turns in different directions
• C. Karel will face the opposite direction
• D. Karel reverts to the starting position

Answer: (A)

Using 'turnLeft()' multiple times in succession results in Karel spinning in circles. Each time Karel executes 'turnLeft()', it moves 90 degrees to the left from its current direction. Therefore, if Karel turns left four times in a row, it will have completed a full 360-degree turn, facing the original direction again. If Karel performs it any other number of times, for example, three times, Karel will be facing a different direction after each turn, ultimately appearing to spin in place. The other potential consequences mentioned do not accurately reflect the behavior of the 'turnLeft()' command. 'Karel turns in different directions' and 'Karel will face the opposite direction' misunderstand how the command increments its facing direction. Reverting to the starting position is also not applicable because Karel does not physically return to its initial coordinates; it only changes its orientation. Understanding this behavior is crucial for programming Karel effectively through diverse challenges.
