This must be weighed in opposition to iostreams benefits of extensibility to manage user-described types, resilient towards stability violations,
In this sort of circumstances, localize using vital extensions and control their use with non-core Coding Recommendations. If at all possible, Make interfaces that encapsulate the extensions so they are often turned off or compiled absent on units that don't guidance These extensions.
To put in writing a base course will be to outline an abstraction (see Items 35 through 37). Remember that for every member perform participating in that abstraction, you should choose:
