What are the key components of a Karel project?

The key components of a Karel project focus on the fundamental aspects that enable Karel to interact with its environment and perform tasks effectively. Tasks refer to the specific goals or objectives that Karel is programmed to achieve, such as moving to a certain position or picking up a beeper. Procedures are sets of instructions or commands that Karel follows to complete these tasks, allowing for organized and reusable code.

Variables play a crucial role in storing information that Karel may need to make decisions or remember the state of the environment. Conditions, often implemented through control structures, enable Karel to make decisions based on certain criteria, such as whether a beeper is present or whether a wall is in front of it. This combination of tasks, procedures, variables, and conditions provides a robust framework for programming Karel effectively, making it critical for any Karel project.

In contrast, the other options focus on concepts that may be relevant in broader programming contexts but do not specifically pertain to the Karel environment and its operation.
