Is there a better way to express nested namespaces in C++ within the header
...ESPACE_BEGIN(Foo, Bar, Baz)
class X { };
NAMESPACE_END(Baz, Bar, Foo) // order doesn't matter, NAMESPACE_END(a, b, c) would work equally well

What is Inversion of Control?
...rol is inverted... instead of the computer accepting user input in a fixed order, the user controls the order in which the data is entered, and when the data is saved in the database.

What is the difference between i++ and ++i?
...prefix (++var) and postfix (var++) versions of ++ do things in a different order with respect to other operations.
It is unsurprising that you'll see a lot of wrong answers to this question. A great many "teach yourself C#" books also get it wrong. Also, the way C# does it is different than how C do...

Algorithms based on number base systems? [closed]
...tly came across a cool algorithm for generating subsets in lexicographical order based on the binary representations of the numbers between 0 and 2n - 1. It uses the numbers' bits both to determine what elements should be chosen for the set and to locally reorder the generated sets to get them into...
How do I return multiple values from a function? [closed]
...riables I'll fold them up in a dictionary. Otherwise I tend to forget the order and content of what I'm returning.
Also, introducing a 'special' structure makes your code more difficult to follow. (Someone else will have to search through the code to find out what it is)
