How can I expand a '#' in C++'s #define?

I want to expose the private members when debuging, like this:

class A {
public:
  void f1();
#ifndef NDEBUG
public:
#else
private:
#endif
  void f2();
};

I want to use macros like:

#define PUBLIC public:
#define PRIVATE \
\#ifndef NDEBUG \
public: \
\#else \
private: \
\#endif

but, well, I know this won't work...

Is there anything that you guys recommend?? Thx in advance.

Edit 01:

My purpose is not to debug my code, but to test the private member functions.

You can't, the preprocessor doesn't have reflection. But you can do it the normal (ugh, arguably...) way:

#ifndef NDEBUG
#define PRIVATE public:
#else
#define PRIVATE private:
#end

Simply define PRIVATE differently depending on NDEBUG:

#ifndef NDEBUG
#define PRIVATE public
#else
#define PRIVATE private
#endif
