The use of the friend keyword is to allow access to protected or private variables of the other class

That is the part I thought I understood.

but you still need an instance of the class to access them.

That is what I have now figured out, but I think only partially.

It's most useful when the friend class inherits the other one

Is the intent most useful or only useful. I am thinking only. I was thinking friend had a rather broader scope.

Class M starts running and creates class C to do a bunch of startup work. C is owned by M but does not inherit from M. C is deleted immediately upon completing its work.

Other than for startup (which requires some 80,000+ data items from a file), nothing in M needs to be public. But this entire app is and always be run in a closed system with strictly controlled ins and outs. I am leery of public variables but that would probably better than sending over a flock of pointers. Does the use of public seem to be my best option.
Thank you for your time
