The Evolution of Functions in Modern C++

In programming, a function is a block of code that performs a computational task. (In practice, people write functions that perform many tasks, which is not very good, but it’s a topic beyond the purpose of this article). Functions are a fundamental concept of programming languages and C++ makes no exception. In fact, in C++ there is a large variety of functions that has evolved over time. In this article, I will give a brief walkthrough of this evolution starting with C++11. Since there are many things to talk about, I will not get into too many details on these topics but will provide various links for you to follow if you want to learn more.
