Before I write about patterns in my upcoming posts, I have to answer one question first. What are the advantages of patterns? As you may assume, I see many advantages, but I boil them down to three points: well-defined terminology, improved documentation, and learning from the best.

Based on my last poll, "Which mentoring program should I implement next?" I recognized that there is a significant demand for writing about "Design Patterns and Architectural Patterns with C++". Today, I would like to present to you my plan for future posts.

Last week, the visitor numbers on this page went from 7,000/day to 25,000/day. Now, I know why. I'm nominated for the "2022 Business Worldwide CEO Awards". You can still vote for me.

Thanks to C++23, constructing containers will become more convenient. Additionally, the ranges library got more new views.

This Sunday, the poll for my next mentoring program ended. There is a unique winner: Design Patterns and Architectural Patterns with C++.

There are more reasons to prefer ranges library above the classical Standard Template Library. The ranges iterators support unified lookup rules and provide additional safety guarantees.

The ranges library in C++20 supports sentinels. Sentinels stand for the end of a range and can be regarded as generalized end iterators.

I will start my next mentoring program in 2023, right after the ending of the current mentoring program, "Fundamentals for C++ Professionals". Now, you have to decide which mentoring program I should implement next.

The algorithms of the ranges library are lazy, can work directly on the container, and can easily be composed. But they have more to offer: projections. A projection is a mapping of a set into a subset. Let me show you in this post what that means:

Working with the Standard Template Library (STL) is much more comfortable and powerful thanks to the ranges library. The algorithms of the ranges library are lazy, can work directly on the container, and can quickly be composed. But there is more to it:
