virtual??

Does anyone know why the
virtualkeyword in C++ has this name? It doesn't seem like a very sensible title for it. There must be some history to it or somthing? Joel HoldsworthUnsure, But maybe it is that you can do thinks in a virtual class or function that you can't do in a base or derived one.

After you understand virtual, please explain me static :-D Yes, even I am blogging now!

Joel HoldsworthIf you have got a deep interest in the history of C++ the book you should get is "The Design And Evolution of C++" by Stroustrup (father of C++). http://www.amazon.com/exec/obidos/search-handle-url/index%3Dblended%26field-keywords%3Ddesign%252520and%252520evolution%252520c%25252B%25252B%26store-name%3Dall-product-search/102-0180251-2256166 As for virtual allow me to speculate. The Ada programming language that appeared AFAIK before C++ has got a keyword "generic", which might be slightly related to "virtual". :) Adam _____________________________________ Action without thought is not action Action without emotion is not life

Joel HoldsworthI think you should ignore the fact that a virtual method may have a default implementation where it's declared. The function is there (declared) but not there at the same time (not implemented). It's virtually there. :) -- ...Coca Cola, sometimes war...

Yeah that kinda makes sense... but it still seems a little flimsy. Why not
overridableor somthing else... somthing more intuitive. Joel Holdsworth -

"generic" makes more sense to me though, than "virtual" Sonork 100.41263:Anthony_Yio

que? are you saying that static is the same as private, and virtual is the same as abstract?
