Is there a readable implementation of the STL? [closed]

Answer 1

For a more recent and thorough explanation of the "rules" of STL (such as iterators), check out a new book co-authored by Stepanov: http://www.elementsofprogramming.com/

If you enjoy mathematics, this book will excite you, because what the authors describe is essentially an algebra of computation. The site includes a sample chapter.

Answer 2

The STL is a highly optimized library that does most of what it does by cleverly exploiting advanced features of C++ and the underlying compiler. Additionally, many things are inlined so there is no real bunch of code to look at like in an application. I'd recommend following Neil's advice.

Answer 3

There is a book The C++ Standard Template Library, co-authored by the original STL designers Stepanov & Lee (together with P.J. Plauger and David Musser), which describes a possible implementation, complete with code - see http://www.amazon.co.uk/C-Standard-Template-Library/dp/0134376331.
