There is some class with very large number of functions. I decided to somehow structure them, give them a meaning and stuff them into structures in public.

class something { int fortyTwo; public: struct fold { void fold1(); void fold2(); void fold3(); } fold; struct take { void take1(); void take2(); } take;

};

How now to allow them to manage data in the parent class? How to define them?

    About the mother class, you correctly noted. You should implement this through inheritance (if it makes sense at all), and not hell hell with such bikes.

    In C ++, it is not possible to access an external class from a nested class (unlike Java, for example).
