How to access names by which data members are declared in c++ and output those names to console

Question

Code:

class A
{
    private:
        int abc;
        string xyz;
}

In the above code, how can I access the names by which data members are declared (abc, xyz) and print them to console?

He's probably looking for reflection, to which I say: wait for C++14/17 ! — user1233963, Sep 06 '13 at 06:19

The only way I can think of is using a macro:

#define PRINT_VAR(x) std::cout << #x << '\n';

C++ doesn't have the reflection capabilities of other languages.

If you mean accessing the names of members, as strings, without knowing those names beforehand, that's not possible - C++ doesn't support reflection.
