Changes since publication

The code in this repository is maintained and may differ slightly from the listings printed in the book. Notable changes (August 2026):

• All examples were formatted with clang-format using the configuration shipped in this repository, so brace placement and indentation can differ from the printed listings.
• Chapter 9, main_strong_types.cpp: getters return values instead of mutable references, narrowing conversions are explicit static_casts, and the _ms literal asserts its range — the example now fully practices what the chapter preaches.
• Chapters 11–17, signal.hpp: the element type is checked to be floating-point, step computation uses the element type instead of float, and the default constructor zero-initializes the array.
• Chapters 11–17, units.hpp: the unit class is constexpr, the literal operators moved into the header (units.cpp was removed), get_mili was renamed to get_milli, and dividing a voltage by a resistance now yields a typed current.
• Chapter 14, main_task.cpp and main_seq.cpp: the test class moved out of main() to file scope. C++20 allows a local class's static member function as a template argument and the GCC 13.2 in the Docker image accepts it, but GCC 12 and older reject it — the change keeps the examples building on older toolchains too.
