What does the 'turnLeft()' function do in Karel programming?

• A. It changes Karel's movement direction right
• B. It enables Karel to climb
• C. It rotates Karel 90 degrees to the left
• D. It stops Karel from moving

Answer: (C)

The 'turnLeft()' function in Karel programming rotates Karel 90 degrees to the left. This means that if Karel is facing north, executing 'turnLeft()' will change Karel's direction to west. Similarly, if Karel is facing east, after the execution of 'turnLeft()', Karel will face north. This function is crucial for navigating Karel through its environment as it allows Karel to change direction without moving forward or backward. Adjusting Karel's orientation enables it to face different walls or obstacles and continues its tasks effectively. The other options do not align with the function of 'turnLeft()' since it specifically pertains to a directional change rather than movement to the right, climbing, or stopping.
