C ++ adds debugging code that only runs when debugging

How the question is explained: I would like to add debugging code that runs only when the program is connected to the debugger. I would suggest that this variable flageither pre-processorwill be different for each compiler ...

In my case, I am using Microsoft Visual Studio 2010 with C ++.

I also use Eclipse on another computer at home running Ubuntu 10.4 and again in C ++.
