The following tests have been done with Visual C++ compiler as it is used by the default Qt Creator install (I guess with no optimization flag). When using GCC, there is no big difference between Mystical's version and my "optimized" code. So the conclusion is that compil...

How to add a default include path for GCC in Linux?
...Try setting C_INCLUDE_PATH (for C header files) or CPLUS_INCLUDE_PATH (for C++ header files).
As Ciro mentioned, CPATH will set the path for both C and C++ (and any other language).
More details in GCC's documentation.

I found the nice resource Standard C++ Containers. Probably this is what you all looking for.

In which scenario do I use a particular STL container?
I've been reading up on STL containers in my book on C++, specifically the section on the STL and its containers. Now I do understand each and every one of them have their own specific properties, and I'm close to memorizing all of them... But what I do not yet grasp is in which scenario each of the...
How can I reliably determine the type of a variable that is declared using var at design time?
...ic Lippert are covered in the code analyzer in the CEDET/Semantic tool for C++ already. There is also a C# parser (which probably needs a little TLC) so the only parts missing are related to tuning the necessary parts for C#.
The basic behaviors are defined in core algorithms that depend on overlo...

Using generic std::function objects with member functions in one class
...:placeholders::_1, std::placeholders::_2);
Or, if your compiler supports C++11 lambdas:
std::function<void(int,int)> f = [=](int a, int b) {
this->doSomethingArgs(a, b);
}
(I don't have a C++11 capable compiler at hand right now, so I can't check this one.)
