When I call M-: (outorg-convert-org-to-outshine) on this Org-mode buffer:

,----
| * ORG SCRATCH
| 
| ** A bit C++
| 
| This program displays a string
|    and then it exits
| 
| This program justs displays a string and exits, variation 2
| #+begin_src c
| #include <iostream>
|  
| int main() {
|   std::cout << "Hello World!";
|   std::cout << std::endl;
|  
|   return 0;
| }
| #+end_src
| 
| #+results:
| : Hello World!
`----

I get

,----
| /* * ORG SCRATCH */
| 
| /* ** A bit C++ */
| 
| /* This program displays a string */
| /*    and then it exits */
| 
| /* This program justs displays a string and exits, variation 2 */
| #include <iostream>
|  
| int main() {
|   std::cout << "Hello World!";
|   std::cout << std::endl;
|  
|   return 0;
| }
| 
| /* #+results: */
| /* : Hello World! */
`----

This uses C, because thats in my org-babel-load-languages, should work
with C++ too. Some modes need a little fix due to inconsistent mode
naming, e.g. ESS[R]:
 
,----
| ;; special case R-mode
|     (if (eq mode 'ess-mode)
|         (funcall 'R-mode)
|       (funcall mode)))
`----

maybe C++ needs this kind of special handling too, let me know if it
does not work out-of-the-box.
