Compile fix. Sorry.
Rename ITEMS to items as it is not a #define anymore.
- Add more documentation
- Replace proper memory allocation with an on-stack buffer to compensate for the growth in line count
Introduce a possible bug-source which could be the goal of the debugging tutorial: A mandatory pre-increment operator. Post-increment wouldn't work here!
- Use allocated memory instead of an on-stack buffer so we actually have a chance of running into memory which we are not allowed to access
- Make the payload array a global variable. This improves the reading flow: The user first sees the input data, then the reference implementation and then the parallel implementation.
Improve documentation, reduce line count.
