But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.

From C++11, std::tuple is an incredible expansion to Modern C++, that offers a fixed-size collection of heterogeneous values. Unfortunately, tuples can be somewhat dubious to manage in a conventional fashion. But, subsequently released C++ standard introduced a few features & helpers that greatly reduce the necessary boilerplate. So, in this article, I will explain the variadic template in C++ with the help of unsophisticated tuple
implementation. And also walks you through a tricky part of tuple i.e.
loop through tuple element. In spite of the fact that I have shrouded the variadic template in my prior article i.e. C++ Template: A Quick UpToDate Look. So, my focus here would be a blend of variadic template & tuple implementation with more up to date C++ gauges.
