While object-oriented software design helps you write more easily maintainable code, companies choose C++ as an OO language for its speed. Object-oriented programming (OOP) in C++ is not automatic - understanding OO concepts and how they map to C++ language features as well as OOP techniques is crucial. You must also know how to distinguish your code by utilizing well-tested, creative solutions, which can be found in popular design patterns. This book will help you to harness OOP in C++ for writing better code. Starting with the essential C++ features that serve as building blocks for the main chapters, this book explains fundamental object-oriented concepts and shows you how to implement them in C++. With the help of practical code examples and diagrams, you'll find out how and why things work. The book's coverage furthers your C++ repertoire by including templates, exceptions, operator overloading, STL, and OO component testing. You'll also discover popular design patterns with in-depth examples and how to use them as effective programming solutions to recurring OOP problems. By the end of this book, you'll be able to employ essential and advanced OOP concepts confidently to create enduring and robust software.
