Features of using virtual functions in object-oriented programs

Novikov Pavel Vladimirovich

The paper discusses the features of using virtual functions in object-orient programs that a common for different programming languages. Techniques of reducing the source code based on the use of virtual functions overridden in the сlass inheritance hierarchy were proposed. The situations with virtual functions were studied, when it is possible both to increase of machine time consumptions and to reduce these consumptions.

Keywords:virtual functions, override of methods, сlass inheritance hierarchy, polymorphic objects, static methods
