Back to Basics: Templates in C++
summary
Covers concrete, up-to-date rules and examples: function and class templates, return-type deduction for mixed-type my_max, class template argument deduction for containers, non-type template parameters (std::array size), variadic templates with recursion vs compile-time if, and use of C++20 Concepts to resolve overloads (push_back vs insert) and produce clearer errors. Demonstrates what compiles, when templates instantiate, where code size or compile-time cost shows up, and which patterns actually work.
