What is the function of 'runToWall()' in the Racing Karel program?

• A. To turn Karel in a circle
• B. To detect the presence of balls
• C. To move Karel until it reaches a wall
• D. To make Karel dance

Answer: (C)

The function 'runToWall()' is designed to move Karel in a straight line until it encounters a wall. This means that Karel will continue to advance forward, step by step, without stopping, until it physically causes its next move to hit an obstacle, which is represented by a wall. This functionality is essential in programming Karel to navigate its environment effectively and is commonly used in scenarios where Karel needs to reach a specific point or limit defined by walls in the grid. The other options relate to different functionalities that are not associated with the purpose of 'runToWall()', which is strictly focused on Karel's movement in relation to walls.
