In rare cases, classes which have users of Weird varieties (for instance reference users) are an exception given that they have peculiar duplicate semantics.

If you must outline any of those five features, this means you would like it to accomplish a lot more than its default conduct – as well as 5 are asymmetrically interrelated. Below’s how:

In that case, have an vacant default or else it is actually impossible to grasp for those who intended to handle all scenarios:

How granular ought to namespaces be? All lessons/features intended to operate together and launched collectively (as outlined in Sutter/Alexandrescu) or something narrower or broader?

This could produce a lot of Wrong positives in some code bases; If that is so, flag only switches that cope with most although not all scenarios

The strings of v are wrecked on exit from bad() and so is v itself. The returned pointer details to unallocated memory try this out within the free of charge retail store.

To seek out function objects and functions defined in a very independent namespace to “customize” a typical function.

Presented an index of C-design allocation capabilities (e.g., fopen()), a checker could also locate employs that aren't managed by a source take care of.

Performance: A change compares in opposition to constants and is usually improved optimized than the he has a good point usual series of assessments in an if-then-else chain.
