What will be the output of the c++program 

#include<iostream> 

  

using namespace std; 

class Base1 { 

 public: 

     Base1() 

     { cout << " Base1's constructor called" << endl;  } 

}; 

  

class Base2 { 

 public: 

     Base2() 

     { cout << "Base2's constructor called" << endl;  } 

}; 

  

class Derived: public Base1, public Base2 { 

   public: 

     Derived() 

     {  cout << "Derived's constructor called" << endl;  } 

}; 

  

int main() 

{ 

   Derived d; 

   return 0;
