Hi all,

I like to ask about templates: as for example we have derived template class:

template class TwoDimArray : public Array < 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 < Array >, 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.
