by Jason Turner | Released July 2016 | ISBN: 9781491961926

Gain new control of your code through a clear understanding of inheritance and polymorphism in C++. Expert Jason Turner teaches you the basics, the gotchas, the implementation and optimization of polymorphism and inheritance through live coded demonstrations and hands-on exercises. To get the most out of the course, learners should already have a basic understanding of C++ programming. Discover the differences between runtime and compile time polymorphism and how to combine them to create powerful constructs Understand class hierarchies in C++ Learn to control aspects of a class using access specifiers Explore covariant return types, multiple and virtual inheritance, private constructors, destructors, mixins, CRTP, and other advanced topics Review the cost and optimization methods of polymorphism, as well as the trade-offs considered when designing libraries Gain the ability to implement the std::any and std::functionJason Turner has over 15 years of programming experience specializing in cross-platform development, scripting of C++ libraries, and automated testing and code quality analysis. Jason is the co-creator and maintainer of the embedded scripting language for C++, ChaiScript, and is the author and curator of the forkable coding standards document, C++ Best Practices. He has spoken at CppCon in Bellevue, Washington, C++Now in Aspen, Colorado, and, is the co-host of CppCast, the podcast for C++ developers.
