First of all I think you should study access control for C++ (i.e
everything in Holder is currently private).
The way you are using std::mem_fun_ref is wrong. The std::vector vec
contains Simple objects and if you want to use std::mem_fun_ref with
the vec you have to define the method Do inside Simple. So, to fix
your code you must move the method Holder::Do to Simple. (Dont forget
to delete the formal parameter, and also include necessary headers and
namespaces)
