Variadic Templates in C++11 / C++14 - An Introduction
summary
Covers concrete how‑tos: implements a variadic print_line using pack expansion and recursion with an explicit zero‑argument base case (required even if never called), demonstrates the overload‑resolution gotcha that produces surprising output during template instantiation, and shows correct use of std::forward. Builds a compile‑time FizzBuzz using make_index_sequence / index_sequence, tuples and a custom apply, verifies results with static_asserts, and shows variadic class templates, template‑template parameters and limitations of variadic lambdas.
