If a class is polymorphic (it has at least one polymorphic function),then for that class, there will be a virtual function table (VFT), which will have all the virtual functions listed one after the ...

Let’s look at the C++ code used to test the timing to walk through inheritance and virtual functions. The parent is the class PinOutputAbstract. It represents an output pin on an Arduino: ...

I have read in several books (including a book on using QT toolkit) warning about using C++'s virtual function because of performance penalty.But they are quite vague on why this is so. Can ...

// c. Virtual functions should be accessed using pointer (*) or reference (&) of Base class type to achieve run time polymorphism. // ADITIONAL NOTES: // 1. Virtual functions cannot be static and also ...

If applied well, refactoring improves the maintainability of the software. However, it is believed that it does so at the sake of performance. Especially in a C++ context, the introduction of virtual ...

The notion of refactoring - transforming the source-code of an object-oriented program without changing its external behavior - has been embraced by many object-oriented software developers as a way ...
