How to initialize non constants in a header?

[dman]

How can i give dynamic assignments in header files.

eg:

//(--in the header file for all "globals"--)
//prototype and definition of myname for all to see.
class _myclass;
_myclass * myname;


//(--this in a sepatate header file, same namespace--)
//my class is in separate file to keep main header file cleaner looking.
class _myclass()
{
blah
blah
blah
};

myname = new _myclass();

I want to organise my headers in such a way to keep my "_internal" stuff out of the way in a separate file while keeping an easy to read set of definitions in my "globals" for other people to see what they are called (with commented help)

It's not a good idea to define or initialize global variables in headers. If two .cpps that are linked together include a header that defines a global variable, you'll get duplicate definition linker error.
If you need to use globals (which is also something you should avoid) you should do it like this:

//file.h
extern T global_var;
extern T2 global_obj;

//file.cpp
T global_var=something;
T2 global_obj(some_other_thing);

If you want to see what 'professional' header files look like, just look at
the header files that come with your compiler.

If you want a challenge- try following through the STL implementation headers
such as for vectors, lists, etc..
