While C++11 ushered in a dramatic improvement to C++, introducing new keywords and constructs that increased your programming efficiency, C++14 brought in incremental improvements that added finishing touches to the features introduced by C++11. This book helps you learn C++ in tiny steps. It has been thoughtfully divided into lessons that teach you the fundamentals of this object-oriented programming language from a practical point of view. Depending on your proficiency level, you will be able to master C++ one hour at a time. Learning C++ by doing is the best way—so try the rich variety of code samples in this book hands-on and help yourself improve your programming proficiency. These code snippets have been tested using the latest versions of the available compilers at the time of writing, namely the Microsoft Visual C++ compiler for C++ and GNU’s C++ compiler, which both offer a rich coverage of C++14 features.
