What will be the output of the following program?

  #include 
   class Base 
   {     
       public:  
       int S, A, M;    
       Base(int x, int y)

          S = y - y;       
          A = x + x;     
          M = x * x;     
       }    
       Base(int, int y = 'A', int z = 'B')     
       {        
          S = y;   
          A = y + 1 - 1;    
          M = z - 1;   
   }  
   void Display(void)    
   {      
       cout" " " " class Derived : public Base
 {  
    int x, y, z;    
    public:

    {        
        x = xx;          
        y = yy;       
        z = zz;   
    } 
    void Display(int n)  
    {      
         if(n)
