...IT code allowed
Above, ap3 quietly "steals" ownership of *ap, leaving ap set to a nullptr, and the problem is that can happen too easily, without the programmer having thought through its safety.
For example, if a class/struct has a std::auto_ptr member, then making a copy of an instance will rel...
What are the best practices for catching and re-throwing exceptions?
... around exceptions. The first is nested exceptions and the second is a new set of exception types offered by the SPL extension (which is now a core extension of the PHP runtime).

Seeding the random number generator in Javascript
