   ocr: olymorpnism Polymorphism in C++ means that you can have many implementations of a particular function defined in a class, yet only one of these definitions will actually be used when the program is complied. To use this reature in C++, there is the keyword "virtual". Dirtual runctions otter derived classes ditterent interpretations of a paselabstract) class runction. The now redetined runction will "over- ride" - the base class runction. Dirtual runctions cannot be global functions in the program.
