What can be used to teach Karel to turn right?

Using functions to teach Karel to turn right is an effective approach because functions allow you to encapsulate a sequence of commands into a single, reusable block of code. In a programming context, if Karel needs to turn right and the default commands only allow for turning left, you can define a function called turnRight. This function would consist of three sequential commands to turn left three times, which effectively results in a right turn.

By creating this function, you can easily call it whenever Karel needs to turn right, promoting code reuse and simplifying your program. This is particularly important in programming, where maintaining concise and understandable code is essential. It allows Karel to perform the action without repeatedly writing out the same commands, making the programming more efficient and organized.

Loops could also replicate this behavior, but they aren't as straightforward for this particular task, as they typically execute a specific command repeatedly rather than defining an actionable function. Conditional statements and variables serve different purposes in programming and would not directly address the need for turning right in Karel's movement logic like functions do.
