Global Variables - Some Points Needing Clarification.

[adt]

I think strategy (b) is perfectly acceptable.

Thanks for your kind confirmation.

Regarding the suggestion:

instead of passing explicitly the global object in the functions' signature, the solution is often to make the functions methods of a class and to make the global object a member of the class, or an instance, so that the pointer to this object is passed implicitly through the self argument.

Would setting up a class be the preferred option even if it were to be called just for a single instance?
