C++ 20 (2a) New Features - Composing Ranges

The video tutorial introduces the concept of ranges in programming, highlighting that as of December 2019, no compiler supports ranges, and the ranges V3 library is the only reference implementation. It demonstrates how to filter even numbers and double them using the Rangers library, and how to generate a sequence of numbers and compute their squares. The tutorial also explains function composition using the bitwise or operator, comparing it to traditional function composition methods.
