Classes C++23 Style - Sebastian Theophil - C++Online 2025

Classes are maybe the most important language feature of C++. It was originally called "C with classes" after all! Classes in C++ have constructors, destructors, base classes, template arguments, attributes, etc. But that is just syntax. When we write and read code, a class should have meaning! It represents a value, a container, a resource, or a state machine. Starting from these different use cases, I will show the best C++23 practices to define common types of classes. How do we define and constrain the life cycle of an object? What special member functions should a class define or not define? What are regular types? What are standard layout types? I will cover the spaceship operator, conditionally explicit conversions, C++26 contracts, reference-qualified member functions, and deducing this. By starting from common use cases, I hope to show not only how to use these C++ features, but also when to use them.

Sebastian has been working at think-cell since it was founded in 2002. In the last few years, among many other things, he has ported think-cell to run on macOS. He also maintains the typescripten project, which lets programmers call JavaScript libraries from C++ code compiled to WebAssembly in a convenient and type-safe way. He enjoys leaving his desk from time to time to talk at international C++ conferences.

C++Online is the annual, online only conference for the entire C++ community. The conference is designed to provide a more accessible option for C++ developers who might find attending other international C++ conferences more difficult or financially restrictive, at a time of year where we traditionally see less in-person cpp conferences due to weather, holidays and other restrictions.
