You could answer such questions yourself:

program Project1;

{$mode objfpc}

type

TMyClass = class
   myarray: array of Integer;
end;

var my:TMyClass;
begin
   my:=TMyClass.Create;
   try
    writeln('After creation the value of my.myarray is 
',PtrUInt(my.myarray));
    SetLength(my.myarray, 0);
    writeln('After SetLength(), value of my.myarray is 
',PtrUInt(my.myarray));
   finally
     my.Free;
   end;
   ReadLn;
end.
