I have a protected variable in a classe, in a file 'B' under a folder F.
I want to reach this variable in a classe in a file 'A' under the same folder F.
Folder F ------> File 1 : Classe with a protected variable X (.h an .cc file)
------> File 2 : Classe where i want to use X (.h and .cc file )
How can I do it?
