What is the function of the command 'turnRight()' in Karel's programming?

• A. Karel changes direction by 90 degrees to the right
• B. Karel picks up a beeper
• C. Karel moves back to its previous position
• D. Karel performs a 360-degree turn

Answer: (A)

The function of the command 'turnRight()' in Karel's programming is to change Karel's direction by 90 degrees to the right. This command is essential for navigating Karel through its environment, allowing it to face different directions as it moves or interacts with objects such as walls, beepers, or other landmarks in its world. When Karel executes 'turnRight()', it rotates 90 degrees clockwise from its current facing direction, which is a fundamental aspect of programming behavior such as solving mazes or following specific paths. The functionality of 'turnRight()' is distinct from actions like picking up beepers, moving backwards, or making a full rotation, which are handled by different commands within Karel's programming environment. This specialized command helps Karel to effectively complete tasks by adjusting its orientation, enabling precise movement and location adjustments.
