What is the purpose of the `turnAround();` command in Karel programming?

• A. It makes Karel jump to a new location
• B. It allows Karel to pick up a beeper
• C. It rotates Karel 180 degrees
• D. It enables Karel to move back to the previous position

Answer: (C)

The `turnAround();` command in Karel programming is designed to rotate Karel 180 degrees. This action effectively turns Karel to face the opposite direction from where it was originally facing. This function is particularly useful for maneuvering within the grid when Karel needs to change its direction to complete tasks or navigate back along its path. Understanding the direction Karel is facing is crucial for executing further commands, as many operations depend on Karel's position and orientation. For instance, after turning around, Karel might be able to move forward, pick up a beeper, or perform other actions in the new direction. This makes the `turnAround();` command a fundamental part of Karel’s ability to navigate and manipulate its environment effectively.
