Wrapping around

Problem

A uint8 wraps around in both directions, and not only when you step over the edge by one. Demonstrate this:

1. Take a uint8 holding 250, add 10 to it, and print the result.
2. Take another uint8 holding 0, subtract one (decrement it), and print the result.

Example

The program prints:

4
255
