Lesmethode :

Virtueel

Algemeen :

In the course What's New in C++23 you learn about the additions and changes introduced in the C++23 standard and how to use them in modern C++ development. The course focuses on developers who already work with C++ and want to understand the latest language features and library enhancements. You examine what has changed compared to earlier standards and where these new capabilities fit within day-to-day software development.

The course covers the most important updates in C++23, including new language functionality and additions to the standard library. You explore the purpose of these changes and their impact on writing, maintaining and modernising C++ code. Attention is given to practical usage and to understanding when the new features provide advantages over existing approaches.

Throughout the course, the new C++23 capabilities are discussed in the context of real-world software development. By comparing new and existing techniques, you gain a clear understanding of how the latest standard can be applied within current codebases. After completing the course, you can evaluate and adopt C++23 features in a structured and informed way.

Doel :

After this course, you can identify the most important additions in C++23 and apply them in your own C++ projects. You can also assess when new language and library features are appropriate for a specific development scenario.

Doelgroep :

Anyone working with C++, such as software developers, application developers and technical specialists who want to update their knowledge of the latest C++ standard.

Voorkennis :

The following prior knowledge is required:

- What's new in C++20 (English)

- Practical experience with C++, the course sometimes goes very deep into C++ because new functionality is often in the more difficult parts of the language.
