style by agregation style.

This group discusses C++. You will find more people familiar with advanced C
style if you post to news:comp.lang. c .

I cross-posted and set the followup to there.

It would seem the important part of design patterns (and of all OO) is
polymorphism. Inheritance and encapsulation are just a framework to
polymorph in.

Classical C polymorphism uses function pointers. So a pattern like Abstract
Template would set a function pointer for each specialized method that the
generic method calls.

This technique is usually called a "callback", and is very common, so OO in
C is probably already very popular.

Hello all, Over the years as I design more database schemas the more I come up with patterns in database design. The more patterns I recognize the more I want to try to design some kind of generic design patterns that can be used and shared amongst many sub-schemas. For example, the grouping of entities. I may have the following tables: employee, product and client. These tables have no direct relationship with each other. But...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
