    Code:
    int main()
    {
        D d;
        cout<<"size of d: "<<sizeof(d)<<endl;//8
        cout<<"i: "<<d.i<<endl;//error
        return 0;
    }
    
    error: i is not member of D.
    but D is derived from B...i is in public part then why this
    error :thinking::thinking::thinking:

    How can we debug code that you don't post?

    You're right though: it SHOULD work. So we need to see the code to find the problem.
    Try to cut B and D down to the least possible (ideally just the i definition).
