21st Century C++

Bjarne Stroustrup discusses the evolution of C++ over its 45-year history, emphasizing the need for contemporary practices in programming with the language. He argues that many developers still use outdated techniques, which can hinder performance, reliability, and maintainability. Stroustrup outlines key concepts for modern C++ programming, including resource management, lifetime management, error handling, modularity, and generic programming. He highlights the importance of using contemporary features of C++ to express ideas more clearly and efficiently, while ensuring type safety and resource safety. The article also introduces guidelines for enforcing modern C++ practices, aiming to help developers transition from older styles to more efficient and safer coding techniques. Stroustrup provides examples to illustrate the advantages of modern C++ features, such as the use of standard library components like `unordered_map` and `vector`, which simplify code and enhance performance. He concludes by stressing that while C++ must maintain compatibility with its past, it can still evolve to meet current programming needs through better practices and features.
