In 2019, my grade for hello.c got 84%, but in 2020, it gets 62%. Why is that?
Maybe it doesn't exactly match the spec any longer? Maybe a different test data set revealed another problem? Maybe you lost more points because they're now also checking style and grading it?
Dunno without seeing code. But why doesn't it score 100%???
I figured out that the problem was with the style50. I fixed and resubmitted it and now I have a 100% score. What @CliffB said about the style was the case. I hope this helps future readers.
