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

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?

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

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.
