Defaulted arguments are one other method to obtain the semantics of overloaded features, so all the explanations not to overload functions apply. Often you have a operate that makes use of default values, however sometimes you wish to override the defaults. Default parameters enable a straightforward means to do this with out having to outline many functions for the uncommon exceptions. Compared to overloading the function, default arguments have a cleaner syntax, with much less boilerplate and a clearer distinction between ‘required’ and ‘optionally available’ arguments.
, and ,(comma) can’t match the evaluation-order semantics of the built-in operators. The hazards of perform overloading apply simply as a lot to operator overloading, if not more so. Overuse of operators can result in obfuscated code, notably if the overloaded operator’s semantics do not follow convention.
Uses of CTAD must additionally follow the final rules on Type deduction. CTAD also suffers from most of the same drawbacks as auto, as a result of they are both mechanisms for deducing all or a part of a variable’s kind from its initializer. CTAD does give the reader more info than auto, however it additionally would not give the reader an apparent cue that information …
