About templetes C++

Question

Hi all I like to ask about templates: as for example we have derived template class: template class TwoDimArray : public Array > { public: TwoDimArray(); } I know that the derived template class snippets above is legal but why? Can anyone explain to me as I thought it is not allowed? And I also like to know what is the purpose of the spaces in the > are they necessary? If so why?

Array > is just another template class so there's no reason why you shouldn't inherit from it just as you can from an 'ordinary' class. The spaces are not significant - it should work just as well if you omit them as I've done above.
