Unlike other C++ programming books, C++ For Dummies considers the "why" just as important as the "how." The features of C++ are like pieces of a jigsaw puzzle. Rather than just present the features, this book will help you to really understand how they fit together. After you finish this book, you'll be able to write a reasonable C++ program, and, just as important, you'll understand why and how it works. C++, as the name implies, is the next generation of the C programming language. The experienced C programmer will find C++ both exciting and frustrating. This book will help you get from C to C++ as painlessly as possible; however, C++ For Dummies, 4th Edition, doesn't assume that the reader knows anything about C language. Anyone, from any programming background, will quickly discover how to Write your first program Create source code Use the Visual C++ help system Build objects Develop C++ pointers Debug your programs This fourth edition of C++ For Dummies begins with basic programming concepts. The book works its way through simple syntax into the care and feeding of basic programs right into object-oriented concepts. Once you've digested the entire content of the book, you should have no trouble impressing your friends and acquaintances at parties. You'll find coverage of all these topics, and more: Declaring variables Performing logical operations Executing loops in a program Writing and using functions Passing pointers to functions Passing objects to functions Using constructors and destructors Declaring static member functions Implementing abstract classes Overloading the assignment operator C++ For Dummies does not cover Windows programming. Finding out how to program Windows in C++ is really a two-step process. First, you need to master C++. That accomplished, you can move on to Windows programming.

Discover how algorithms shape and impact our digital world All data, big or small, starts with algorithms. Algorithms are mathematical equations that determine what we see—based on our likes, dislikes, queries, views, interests, relationships, and more—online. They are, in a sense, the electronic gatekeepers to our digital, as well as our physical, world. This book demystifies the subject of algorithms so you can understand how important they are business and scientific decision making. Algorithms for Dummies is a clear and concise primer for everyday people who are interested in algorithms and how they impact our digital lives. Based on the fact that we already live in a world where algorithms are behind most of the technology we use, this book offers eye-opening information on the pervasiveness and importance of this mathematical science—how it plays out in our everyday digestion of news and entertainment, as well as in its influence on our social interactions and consumerism. Readers even learn how to program an algorithm using Python! Become well-versed in the major areas comprising algorithms Examine the incredible history behind algorithms Get familiar with real-world applications of problem-solving procedures Experience hands-on development of an algorithm from start to finish with Python If you have a nagging curiosity about why an ad for that hammock you checked out on Amazon is appearing on your Facebook page, you'll find Algorithm for Dummies to be an enlightening introduction to this integral realm of math, science, and business.
