CopperSpice: Inheritance
▻http://isocpp.org/feeder/?FeederAction=clicked&feed=All+Posts&seed=http%3A%2F%2Fisocpp.org%2Fblog%2F2

New video on the CopperSpice YouTube Channel:

Inheritance

by Barbara Geller and Ansel Sermersheim

About the video:

In this video, we look at the full variety of inheritance mechanisms that C++ provides. The C++ object model allows several different types of inheritance relationships, both single and multiple, as well as support for composition. Some of the terminology around these inheritance relationships can be quite confusing, and we present some best practices for avoiding miscommunication and misunderstandings. We address questions of how these features interact and why you would choose one type of inheritance over another.

CopperSpice: Sequencing

New video on the CopperSpice YouTube Channel:

Sequencing

by Barbara Geller and Ansel Sermersheim

About the video:

This video discusses sequencing and the ordering of expressions. We look at how the idea of sequence points was redesigned as the more general system of sequencing in C++11 and how new sequence rules were added in C++17 to further constrain expression evaluation. We also show how a detailed understanding of side effects and their interaction with sequencing is required to avoid undefined behavior.

CopperSpice: Overload Resolution

New video on the CopperSpice YouTube Channel:

Overload Resolution

by Barbara Geller and Ansel Sermersheim

About the video:

This video discusses overload resolution and the complications involved in debugging when the compiler does not choose the overload you think it should. This video was very interesting to put together, since we had no idea how much of the standard you need in order to understand the intricacies of overload resolution. Not only is overload resolution complex, but you also need to understand the details of type conversions and template argument deduction.
