Back to Basics: Function and Class Templates
summary
Covers concrete mechanics: writing function and class templates (swap, rational, bitset), how the compiler performs template instantiation versus an explicit specialization, when to use typename for dependent names, and how C++17 changes things (class template argument deduction and inline variables). Explains template parameter lists, non-type parameters, static data members and where to place definitions, template argument deduction limits (not from return types), and explicit instantiation with extern template for link-time control.
