An Overview of the New C++ (C++11)

Scott Meyers

Specification of the new version of C++ (“C++11”) is finally complete, and many compilers already offer a wealth of features from the revised language. And such features! auto-declared variables reduce typing drudgery and syntactic noise; Unicode, threading support, and alignment control address important functionality gaps; and rvalue references and variadic templates facilitate the creation of more efficient, more flexible libraries. The standard library gains resource-managing smart pointers, new containers, additional algorithms, support for regular expressions, and more. Altogether, C++11 offers much more than “old” C++. This intensively technical seminar introduces the most important new features in C++11 and explains how to get the most out of them.

Course Highlights

Participants will gain:

  • Knowledge of the most important C++11 features and how they help produce better programs.
  • Insights into how new features solve important problems.
  • Understanding of which features are useful primarily to library writers, which to class authors, and which to virtually all C++ developers.
  • Availability information regarding which features are available on which platforms.

Who Should Attend

Designers and developers who are using, considering using, or wish to know about the expanded capabilities of C++11. Attendees should be experienced with C++ and comfortable with its primary features (e.g., classes, templates, inheritance, STL, etc.). Familiarity with threading concepts (e.g., threads and mutexes) is helpful, but is not essential.

Format

Lecture and question/answer. There are no hands-on exercises, but participants are welcome – encouraged! – to bring computers to experiment with the material as it is presented.

Length

Three full days (six to seven lecture hours per day).
