What can be used to teach Karel to turn right?

To teach Karel to turn right, the most effective approach is through the use of functions. Functions allow you to create a specific set of instructions that can be reused throughout the program. By defining a function called something like "turnRight," you encapsulate the series of commands needed for Karel to turn right, such as turning left three times. This improves code organization and readability, making the program easier to manage.

Functions are especially useful in Karel programming because they allow you to abstract complex behaviors into a single command, promoting code reuse and reducing redundancy. By using a function for turning right, you can simply call that function whenever Karel needs to make that turn, rather than repeating the same series of commands each time. This enhances the overall efficiency of the code and makes it much easier to implement changes later.
