Hi, The Emacs C++ mode is called c++-mode. In babel C++ is C++. Hence, the following problematic case holds.
With the block, (lowercase c) #+begin_src c++ ... #+end_src I can edit it in the c++-mode and get nice fontification, but I can't execute it. With (capital c) #+begin_src C++ ... #+end_src I can execute the block in Org, but I can't edit it in c++-mode. I'm not very knowledgeable about Babel, so the best fix I could find was adding (defalias 'C++-mode 'c++-mode) to the top of ob-c.el (after requiring cc-mode). Of course C++ could also be renamed c++, but the correct name does in fact seem to use capitals (cf. Wikipedia). Ob-template didn't mention how to associate a language with a given mode.
