Is C a wasted/useless language?
Given the chance, I can''t not post my favorite peice of C that isn''t valid C++ (a little code never hurt anyone). Commonly known as the struct hack, it part of the C99 standard but not in any C++ standards. C++ has different ways of doing almost the same thing (some would argue better ways), but still...

DX is C based, so you won''t find anything that is C++:ish in those headers.
Uhh no. It may have been originally, but it is now more C++ than C.

Try not to confuse COM with C++. COM can be done just as easily in Visual Basic as in C and even C++. Does that make DirectX more VB than C++?
C certainly won''t die in that it seems to be a model for plenty of other languages (Java, C#, Python, etc.). Beyond that, everything that''s possible in C++ is possible in C. Harder, maybe, but completely possible. And that includes the Object-Oriented paradigm. Anytime you kids do anything procedural in C++, you''re using C. Anytime you enjoy the low-level nature of C++, you''re enjoying an intrinsic property of C. Furthermore, no single language is the best for all things, so C or whatever other language will always have a place (there are times when C++ is simply overkill; its facilities just add overhead with no extra reliability or any of the other things promised).
