虚基类的值由最远派生类赋值

#include<iostream>
using namespace std ;

	{
		cout<<"Initializing Base..."<<endl;
		this->basee = base ;

		cout<<basee<<endl;
	}

public:
	Base1(int base1 ,int base1base ):Base(base1base)
	{
		this->base11 = base1 ;
		cout<<"Initializing Base1..."<<endl;
	} 
};
class Base2:virtual public Base
{
	int base22 ;
public:
	Base2(int base2, int base2base):Base(base2base)
	{
		this->base22 = base2 ;
		cout<<"Initializing Base2...."<<endl;
	}
};
class Derived : public Base1, public Base2
{
	int derived ;
public:
	Derived(int derivied , int derivedbase , int base1 , int base1base ,  int base2 , int base2base ) : Base(derivedbase),Base1(base1,base1base),Base2(base2,base2base)
	{
		cout<<"Initializing Derived..."<<endl;
		this->derived = derivied;
	}
};
int main()
{
	int derivied = 1 ;
	int derivedbase = 2 ;
	int base1 = 3 ;
	int base1base = 4 ;
	int base2 = 5 ;
	int base2base = 6 ;
	Derived d(derivied , derivedbase,base1,base1base,base2,base2base);
   d.show();
	return 0 ;
}

　　

输出为 derivedbase=2
