Programming

Consider the following program

 Program P2 
                   var n: int: 
                   procedure W(var x: int) 
                   begin 
                          x=x+1; 
                          print x;   
                   end 

                procedure D 
                begin  
                          var n: int; 
                          n=3; 
                          W(n);  
                End 
            begin               //beginP2 
                n=10; 
                D; 
            end  

If the language has dynamic scoping and parameters are passed by reference, what will be printed by the program?
