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->objBase.x ; 
     }  
    ~GateDerived()  
     { } 
 };
  int main() 
  {    
      GateDerived objDev(11, 22);    
      return 0;
  }
