GoKawiilBjarne Stroustrup's C++ Style and Technique FAQ
Modified February 26, 2022
These are questions about C++ Style and Technique that people ask me often. If you have better questions or comments on the answers, feel free to email me (bs at cs dot tamu dot edu). Please remember that I can't spend all of my time improving my homepages.
I have contributed to the new, unified, isocpp.org C++ FAQ maintained by The C++ Foundation of which I am a director. The maintenance of this FAQ is likely to become increasingly sporadic.
Also, the C++ Core Guidelines contains a large set of maintained guidelines for the use of modern C++.
For more general questions, see my general FAQ.
For terminology and concepts, see my C++ glossary.
Please note that these are just a collection of questions and answers. They are not a substitute for a carefully selected sequence of examples and explanations as you would find in a good textbook. Nor do they offer detailed and precise specifications as you would find in a reference manual or the standard. See The Design and Evolution of C++ for questions related to the design of C++. See The C++ Programming Language for questions about the use of C++ and its standard library.
