What is the function of the isAtGoal() method?

• A. It checks if Karel is facing the right direction.
• B. It checks if Karel has reached its predefined goal position.
• C. It determines Karel's current location on the grid.
• D. It identifies obstacles in Karel's path.

Answer: (B)

The isAtGoal() method is specifically designed to determine whether Karel has arrived at a designated goal position on the grid. This function is crucial for controlling Karel's movement towards a target location within the programming environment. When isAtGoal() returns true, it indicates that Karel is at the position it was intended to reach, enabling the program to proceed to the next set of instructions or to stop if no further actions are required. This method plays a pivotal role in various algorithms where reaching a specific location is the end condition. For instance, in scenarios involving maze navigation or targeted tasks, knowing when Karel has reached its goal helps ensure the program behaves as expected and allows Karel to complete its programmed tasks effectively.
