Back To Basics: Overload Resolution
summary
Condenses the C++ standard to the concrete rules that decide overload choice: ranking of standard conversions (exact match, promotions vs conversions), template argument deduction vs non-templates, user‑defined and ellipsis conversions, and the C++20 concepts tie‑breaker. Shows surprising ambiguites (int→long vs int→char, 32–35 page standard clauses cited), runnable examples and quizzes, and practical fixes: mark constructors explicit, use SFINAE/concepts or explicit casts, add/remove overloads. Companion code lives on GitHub (CopperSpice, DoxyPress, cs_string, cs_signal, libGuarded) and examples behave consistently across compilers.
