What will be the out of the following program?

 #include 
  class GateBase
  {    
      public:   
      int x, y;    
      public:   
      GateBase(int xx = 0, int yy = 0)        
      {     
          x = xx;     
          y = yy;  
      }  
  }; 
  class GateDerived : public GateBase 
  {   
       private:    
         GateBase objBase;  
      public:    
      GateDerived(int xx, int yy) : GateBase(xx), objBase(yy)     
       {      
          cout this->x   " "               
               this->y   " "   
               " "    
               " ";  
     }   
    ~GateDerived()  
     { } 
 };
 int main() 
 {    
      GateDerived objDev(11, 22);  
      return 0;
 }
