9.18.8.Inherit base class twice

#include <iostream>

using namespace std;



class base {

public:

  int i;

};



class derived1 :  public base {

public:

  int j;

};



class derived2 : public base {

public:

  int k;

};



class derived3 : public derived1, public derived2 {

public:

  int sum;

};



int main()

{

  derived3 ob;



  ob.derived1::i = 10; // scope resolved, use derived1's i



  return 0;

}
