C++ 20 (2a) New Features - Rationale for Ranges

The video tutorial explains the concept of ranges in C++ and how they provide a higher level of abstraction compared to iterators. It discusses the limitations of composing functions with standard library algorithms and demonstrates how ranges can simplify code by reducing unnecessary copies and memory allocations. Examples are provided to illustrate the manipulation of standard containers using ranges.
