This presentation by Bjarne Stroustrup who began developing C++ (initially called “C with Classes”) in 1979, is about to explain what’s great about C++, C++20, as a modern language. Bjarne explains how do classes, templates, and lambdas fit together? What have constructors and destructors to do with exceptions? What’s in the standard library? How can we start using C++? And finally he has few comments about how to get from older styles of C++ use to modern C++ and point to areas where we need to improve C++ further.
