Do classes have external linkage?

Question

I have 2 files A.cpp and B.cpp which look something like

A.cpp
----------
class w
{
public:
    w();
};


B.cpp
-----------
class w
{
public:
    w();
};
         


        

Answer 1

Classes have no linkage to be pedantic.

Linkage only applies to symbols, that is, functions and variables, or code and data.
