ptr->a();

(*ptr).a();

Since you are asking for it in the comments. What you are probably looking for can be found in the Standard (5.2.5 Class member access):
The compiler will produce the exact same instructions and it will be just as efficient. Your machine will not know if you wrote “->” or “*.”.
