C++20 views are not limited to the adaptors provided by the standard library. When an operation cannot be expressed through their composition, you can implement a custom view.

This article demonstrates the process by building a lazy, SAX-like XML parser. Along the way, it explains how views, iterators, and sentinels work together, which standard concepts they must satisfy, and how to make a custom view compatible with range-based loops and standard views.

A practical look at how to prepare for C++ coding interviews without treating LeetCode as a replacement for real engineering work: train fast thinking, use modern STL, practice std::ranges, and turn interview preparation into useful daily C++ training.

C++20 coroutines provide the low-level machinery for suspendable functions, but not a complete async runtime. This article explains what coroutines are, how std::generator makes lazy value generation practical, and how libraries such as libcoro provide tasks, schedulers, and thread pools for real projects.

C++20 concepts make template requirements explicit, reusable, and easier to diagnose. This article explains how concepts improve generic code, participate in overload resolution, simplify class template specialization, and help build a clear vocabulary for type requirements.
