cppreference.com: The Containers library is a generic collection of class templates and algorithms that allow programmers to easily implement common data structures like queues, lists and stacks.   There are three classes of containers — sequence containers, associative containers, and unordered associative containers — each of which is designed to support a different set of operations.

We know lots of folks are either coming back to C++, coming to C++, or have never left C++. This lecture series, in n parts, is for all of you! Only STL can make that work (novice, intermediate, and advanced all bundled together and presented in a way only STL can do.)

C9 Lectures: Stephan T. Lavavej – Core C++

In the following series, learn all about STL from the great Stephan T. Lavavej, Microsoft’s keeper of the STL cloth (this means he manages the partnership with the owners of STL and Microsoft, including, of course, bug fixes and enhancements to the STL that ships as part of Visual C++).

• Part 1 (sequence containers)
• Part 2 (associative containers)
• Part 3 (smart pointers)
• Part 4 (an extended example of using the STL to solve Nurikabe puzzles)
• etc

Alexander Alexandrovich Stepanov (Russian: Александр Александрович Степанов) (born November 16, 1950 in Moscow) is the primary designer and implementer of the C++ Standard Template Library [1], which he started to develop around 1992 while employed at HP Labs. He had earlier been working for Bell Labs close to Andrew Koenig and tried to convince Bjarne Stroustrup to introduce something like Ada Generics in C++.

Elements of Programming – (November 3, 2010) Speakers Alexander Stepanov and Paul McJones give a presentation on the book titled “Elements of Programming”. They explain why they wrote and attempt to explain their book. They describe programming as a mathematical discipline and that it is extremely useful and should not be overlooked.

Iterators Must Go (Google Docs)

• download latest Boost version
• unpack it
• run “Visual Studio 2008 Command Prompt” bat file

build bjam

• go to %BOOST%/tools/jam/src folder
• run build.bat file
• copy bjam.exe file to %BOOST%/bin folder from %BOOST%/tools/jam/src/bin.ntx86 folder

build boost

• go to %BOOST% folder
• compile Boost using bjam.exe:

bin\bjam.exe –build-dir=”C:\Dev\Libs\boost\build-boost” –toolset=msvc –build-type=complete stage

std::map<wstring, wstring> map1;
std::map<wstring, wstring> map2(map1);
std::map<wstring, wstring> map3(map2.begin(), map2.end());

map1.insert(map3.begin(), map3.end());
map2 = map3;
std::copy(map2.begin(), map2.end(), inserter(map1, map1.end()));
