The first exercise introduces the `packed` keyword as an alternative for bitwise operations. Its main goals are establishing a solid understanding of field order and conveying the fact that packed containers are basically integers. It introduces the concept of container layouts and briefly explains the default `auto` layout before introducing the `packed` layout (but doesn't touch `extern` at all). The exercise also presents a real-world use case for packed containers, namely LZ4 frame descriptors. Furthermore it covers equality comparisons between packed containers. The second exercise talks about switch statements with packed containers and goes into some more detail on packed unions. |

No Peeking! :-)
Welcome to the ziglings/patches directory. This is how ziglings is tested.
The patches fix the broken exercises so that they work again, which means the answers are here, so no peeking!
Éowyn
A Bash shell script named eowyn.sh dwells here. She heals the little broken
programs and places them in a healed directory, which is NOT committed to the
repo.
$ patches/eowyn.sh
(If you invoke her from elsewhere, she'll come here to ply her trade.)
The build.zig build script at the heart of Ziglings has a top-secret option
which tells it to test from the patches/healed/ dir rather than exercises/:
$ zig build -Dhealed [step]
Éowyn tests all healed programs using this secret option.
Gollum
Another Bash shell script named gollum.sh may also be found. He snatches the
original answers and stows them in his secret answers stash. If you leave him
alone, he'll leave you alone.
