That's odd...

Now that I can compile ".cpp" files in Microsoft's Visual C++ 2008
I still can't figure out how to compile a ".c" file, since
every time I do it, the extension is changed to ".c.cpp"

Any tips? (I mean here, those folks that have been used Visual C++
before, because I need
some advice on concrete terms, such as: "go to View-Other Windows- etc
etc" than click here, etc )

Thanks in advance.
