Message:

Member functions of Vector class may be called while going over an iteration of a list containing Vectors, thanks to member function pointers.

• Unit test ActOnAllTest is the basic class for showing, how we can use any member function of Vector:: and make it act globally over a list of vectors.
• this is incorporated into the definition of class molecule for the vectors contained in the atoms chained list.
