Notebook C++: Tips and Tricks with Templates
Notebook C++: Tips and Tricks with Templates
About the Book
One of the problems that C++ programmers face using templates is understanding the complex syntax. Mastering Templates can be a game-changer when programming C++, as it is a powerful feature for writing clean code.
In this book from the Notebook C++ series, the author Andreas Fertig shows you tips and tricks on how to write templates efficiently. It starts with the basics, like the different template parameter types and techniques like always_false. You’ll then learn more about best practices. For example, where to put the enable_if and how to disable a special member function.
Notebook C++: Tips and Tricks with Templates is a quick-reference book where you can find the information you need for programming the moment you need it.
