Enter a world of hardcore back-end, server-side enterprise programming on the .NET platform. This book presents some of the important aspects of the C++/CLI language that often become a barrier preventing programmers from exploring further. The C++/CLI Primer is a powerful but compact book that will guide you through that barrier. Many of today's complex transactions and enterprise applications count on C++/CLI. Visual Studio 2015 and earlier versions support C++/CLI if you program using an IDE. C++/CLI is unattractive, clumsy, and hard when compared to other modern languages that run on the .NET platform. That's because it is powerful. Like light that can be viewed as a wave or particle, C++/CLI can be exercised as an unmanaged or managed or actually as the sandwich language to do mixed mode programming, which is its real power. That's also why it is unique. What You'll Learn Discover C++/CLI and why is it used in .NET programming Work with types, primitive types, object creation, and managed and abstract classes Use abstract classes in C++/CLI Harness the power of nullptre Implement code that uses boxing/unboxing Use equality/identity, properties, enums, strings, arrays, and more Who This Book Is For Experienced Microsoft .NET application developers, familiar with .NET framework and C++.

Make your Swift apps agile and sound with this short step by step guide. You'll learn about unit testing, mocking and continuous integration and how to get these key ingredients running in your Swift projects. This book also looks at how to write your Swift apps using test driven development (TDD). Agile practices have made major inroads in iOS development, however it's very unusual to see something as basic as unit testing on a Swift application. Done correctly, Agile development results in a significant increase in development efficiency and a reduction in the number of defects. Apple has released unit testing and code coverage frameworks for Swift development in XCode. Up until now getting unit testing up and running in Swift was not for the faint-hearted. Thankfully now, there is no excuse other than a lack of information on where to get started. iOS developers are faced with their own set of problems such as tightly coupled code, fragmentation, immature testing tools all of which can be solved using existing Agile tools and techniques. Swift Programming Using Agile Tools and Techniques is your solution to handling these tasks. What You Will Learn Write unit tests in Swift Write an application using test driven development Examine GUI testing, refactoring, and mocking frameworks Set up and configure a continuous integration server Measure code coverage Who This Book Is For Swift developers and would be mobile app testers will benefit from the guidance in this book.

While compilers for high-level programming languages are large complex software systems, they have particular characteristics that differentiate them from other software systems. Their functionality is almost completely well-defined - ideally there exist complete precise descriptions of the source and target languages. Additional descriptions of the interfaces to the operating system, programming system and programming environment, and to other compilers and libraries are often available. The book deals with the optimization phase of compilers. In this phase, programs are transformed in order to increase their efficiency. To preserve the semantics of the programs in these transformations, the compiler has to meet the associated applicability conditions. These are checked using static analysis of the programs. In this book the authors systematically describe the analysis and transformation of imperative and functional programs. In addition to a detailed description of important efficiency-improving transformations, the book offers a concise introduction to the necessary concepts and methods, namely to operational semantics, lattices, and fixed-point algorithms. This book is intended for students of computer science. The book is supported throughout with examples, exercises and program fragments.
