cppreference, C++20 and 23, and reading other people's code.

Part 2

This chapter needs a key

The last chapter. What this book left out and where to learn it, how to read the documentation without drowning, what the newer standards changed, and how to get better at this from here.

You'll build: Read somebody else's program. Pick a real codebase, understand one file, and find out what you can now do.
