let's have, or going write, set of related functions. let's they're math-related. organizationally, should i: write these functions , put them in mymath namespace , refer them via mymath::xyz() create class called mymath , make these methods static , refer mymath::xyz() why choose 1 on other means of organizing software? by default, use namespaced functions. classes build objects, not replace namespaces. in object oriented code scott meyers wrote whole item effective c++ book on topic, "prefer non-member non-friend functions member functions". found online reference principle in article herb sutter: http://www.gotw.ca/gotw/084.htm the important thing know that: in c++ functions in same namespace class belong class' interface (because adl search functions when resolving function calls). namespaced functions, unless declared "friend," have no access class' internals, whereas static methods have. this means, examp
