C++ define class member struct and return it in a member function

Question

private:
    struct userInfo
    {
        int repu, quesCount, an         


        

Answer 1

If the member function is public, then the return type must be publicly visible! Therefore, move the inner struct definition into the public section.

Note also that it must be defined before the function that uses it.
