In my previous article the mess of virtual functions, I show how easily they introduce bugs and propose language extensions to fix it. Several comments suggested an alternate solution with the “non-virtual […]
Virtual functions, though generally a blessing, have a defect-prone dark side. No language, that I know of, provides a way to encode when the base class should be called. This leads to […]
A new technology I’m trying has a curious domain-specific extension for OpenGL graphics. It introduces a block concept allowing for modular shader code. From a language standpoint I was uncertain what to […]
It is important to write exception-safe code. A truly exception-safe function produces no side-effects when an error occurs. It returns to the caller with the exact state of the system as prior […]
Sometimes the simplest of things have complex answers. In programming we like to think of simple data types, but in reality there aren’t any. While it is nice to consider things as […]
In the article on “How Polymorphism Works: Part 1” we learned how to create virtual functions. The method which we chose has at one significant problem with it: it requires a lot […]
Polymorphism: the core of object oriented programming. Most modern languages have some concept of interfaces, virtual functions, and classes. Though each language differs in details, and may have specialized concepts, the core […]
Do you know what it takes
to become a great programmer?
