## Delivering safe C++ Bjarne Stroustrup Columbia University www.stroustrup.com  ## Overview • The challenges of safety Government have begun initiatives to drive the culture of software development towards utilizing memory safe languages. · ... • NSA advises organizations to consider making a strategic shift from programming provide little or no inherent memory protection, such as C/C++, to a memory safe language when possible. Some examples of memory safe languages are C#, Go, Java, Ruby $ ^{™} $ , and Swift $ ^{®} $ . • NSA:

21 October 24-29 ## Exceptional C++ CppCon 2021 October 25 $ ^{th} $ ## Abstract When writing code we usually focus our attention on the happy paths - that’s where the interesting stuff happens. But exceptions are a powerful mechanism of maneuvering execution on the unhappy path. Even if std::exception and related machinery are not your cup of tea, you might care about hardware faults or OS signals happens when an exception occurs, both at the application level and the OS level. We'll explore the unwind process, the compiler generated code, the CRT hooks available and other exception internals. As
