What variable type is used to represent Karel's position in the grid?

In Karel programming, Karel's position on the grid is indeed maintained internally, which means that Karel does not explicitly use a variable type like integer, string, or boolean to represent this information. Instead, Karel's position is an inherent aspect of its state, tracked without the need for the programmer to manipulate it as a standalone variable.

This internal tracking system allows Karel to reference and update its position automatically as it moves around the grid. The abstractions in Karel's programming model simplify tasks by handling positional data behind the scenes, making it easier for users to focus on writing code for actions and logic without delving into position management.

In contrast, integer, string, and boolean types are used for other programming tasks but do not directly represent Karel's grid position, which reinforces the idea that Karel's position is fundamentally internal and managed by the system itself.
