Help with C++ interfacing

I'm very new to programing in C ++ and C#. However I would like to use either programing language to communicate with my arduino. Right now I have a simple sketch uploaded onto my arduino board that turns on a LED when the user types 'H' in the serial monitor window.

Now I would like to interface this code with C++. Can anyone please tell me the best way to do this? Or if anyone has some sample C++ code that they can send me to get me started, that would be great too. Any help on getting me started would be greatly appreciated!

Thanks, Bella
