Profiles for Simplicity and Guarantees - Bjarne Stroustrup - CppCon 2026

The C++ community is growing fast. C++ is being used in critical applications. C++ can be used in ways that ensures correctness, simplicity, performance, and maintainability. How can we ensure that it is used is such desirable ways? How can we teach new and old C++ developers to do so?

The general strategy is called “subset of superset” and is based on the idea that by extending (“supersetting”) by adding libraries, we can simplify static analysis to where we can remove undesirable uses (“subsetting”) without damaging expressiveness or efficiency. Where run-time checks are necessary, such as to catch out-of-range accesses in hardened libraries, static analysis can be used to minimize the number of checks.

The strategy is supported by the “Profiles” framework, that allows us to require or suppress specific sets of guarantees, called profiles.

As examples, I show how to eliminate uninitialized-object errors and container-invalidation errors (a kind of dangling pointer errors) using the profiles framework and implementations of the “Initialization” and “invalidation” profiles. Both with zero run-time cost.

Bjarne Stroustrup

Bjarne Stroustrup is the designer and original implementer of C++ as well as the author of The C++ Programming Language (4th Edition) and A Tour of C++ (3rd edition), Programming: Principles and Practice using C++ (2nd Edition), and many popular and academic publications. He is a professor of Computer Science in Columbia University in New York City. Dr. Stroustrup is a member of the US National Academy of Engineering, and an IEEE, ACM, and CHM fellow. He received the 2018 Charles Stark Draper Prize, the IEEE Computer Society's 2018 Computer Pioneer Award, and the 2017 IET Faraday Medal. He did much of his most important work in Bell Labs. His research interests include distributed systems, design, programming techniques, software development tools, and programming languages. To make C++ a stable and up-to-date base for real-world software development, he has been a leading figure with the ISO C++ standards effort for more than 30 years. He holds a master’s in Mathematics from Aarhus University, where he is an honorary professor in the Computer Science Department, and a PhD in Computer Science from Cambridge University, where he is an honorary fellow of Churchill College.
