The Implementation of Value Types

by Lawrence Crowl

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Predefined value types are central to C++ efficiency and robustness. More importantly, C++ provides mechanisms that enable programmers to create high-quality value types, programmers are not limited to the small predefined value types. However, implementing a high-quality type requires attention to several problems, among them portability, representation, efficient copying, efficient parameters, aliasing, constant initialization, and constant expressions. We present the issues and several approaches to implementing high-quality value types.
