What does the command turnRight(); do?

• A. Karel turns 180 degrees
• B. Karel moves one square to the right
• C. Karel turns 90 degrees to the right
• D. Karel stops moving

Answer: (C)

The command turnRight(); is designed to make Karel turn 90 degrees to its right. This is a fundamental movement instruction within the Karel programming environment, allowing Karel to change its orientation in a specific direction, enabling it to navigate through its surroundings effectively. By executing this command, Karel maintains its position while changing the direction it faces, which plays a crucial role in programming tasks that involve maneuvering through grid-based environments.

Significantly, understanding this command is vital for creating movement sequences that guide Karel towards objectives, whether that involves navigating to a particular location or organizing objects within the grid.
