How to optimize for-comprehensions and loops in Scala?
...y. You should note note that the use of return in isEvenlyDivisible is not free. The use of return inside the for, forces the scala compiler to generate a non-local return (i.e. to return outside it's function).
This is done through the use of an exception to exit the loop. The same happens if you ...
When is a C++ destructor called?
...o replace an object with another object of the same type but don't want to free memory just to allocate it again. You can destroy the old object in place and construct a new one in place. (However, generally this is a bad idea.)
// pointer is destroyed because it goes out of scope,

Conclusion
The memory system of a processor is quite a bit more complex and involved than described here; a discussion on how an x86 processor actually addresses memory ...

Is it faster to count down than it is to count up?
