Introduction to C++ Friends, Nesting, Static Members, and Templates

Using Separate Files

•There are some restrictions.

•Templates defined in an unnamed namespace cannot be exported.

•But, an exported template only needs to be declared in the file in which it is instantiated.

•Declaring member functions of a class template as exported means that its members can be exported and used in other files.

•If the keyword export was not used, the definition of the function must be within the scope of where we define the objects. This would require that we include the implementation file in our header file and ultimately in client code as well (e.g., t_class.h could include t_class.cpp)
