About the Book

This book is a combination of the following two books :Advanced C++ FAQs: Volume 1 : Fundamentals

Advanced C++ FAQs: Volume 2 : Generic Programming

Advanced C++ FAQs: Volume 1 : Fundamentals

This book is not an introduction to C++. It assumes that the reader is aware of the basics of C++98 and C++03 and is keen to expand her horizon to latest and greatest in the present and future of C++, including C++11 and C++1y(aka C++14). It contains selected fundamental problems with detailed solutions to all of these which will help the reader to hone her skills to solve a particular problem.

Advanced C++ FAQs: Volume 2 : Generic Programming

This book is sequel to the first volume Advanced C++ FAQs : Volume 1 : Fundamentals. It contains selected generic programming problems with detailed solutions.
