Ebook The C++ programming language (Fourth Edition) present content: C++ programmers who want to know what the latest ISO C++ standard has to offer, C programmers who wonder what C++ provides beyond C, and people with a background in application languages, such as Java, C#, Python, and Ruby, looking for something ‘‘closer to the machine’’ – something more flexible, something offering better compile-time checking, or something offering better performance.

The primary purpose of this book is to help scientists and engineers working intensively with computers to become more productive, have more fun, and increase the reliability of their investigations. Scripting in the Python programming language can be a key tool for reaching these goals [27,29]. The term scripting means different things to different people. By scripting I mean developing programs of an administering nature, mostly to organize your work, using languages where the abstraction level is higher and programming is more convenient than in Fortran, C, C++, or Java.

The popular C# programming language combines the high productivity of rapid application development languages with the raw power of C and C++. Updated to cover the new features of C# 4.0, including dynamic binding, named and optional parameters, and covariant and contravariant generic types, this release takes the language to the next level by adding the ability to cleanly write programs that don't rely on static type definitions. This allows dynamic programming languages such as Python, Ruby, and JavaScript to feel native to C#.

Developers the world over talk about Programming Ruby and the Ruby language. “Ruby is a wonderfully powerful and useful language, and whenever I’m working with it, this book is at my side.” Martin Fowler, Chief Scientist, ThoughtWorks “If your world revolves around Java, as mine did, then you need this outstanding book to learn all the wonderful things you’re missing. There’s just one catch: you’ll be spoiled from then on. Indeed, after reading just a few pages of Programming Ruby, programming in any language other than Ruby will feel like you’re pushing rope.

For developers who have learned the elegant and highly productive Ruby language, it can be a real drag to switch back to a traditional static programming tool like Objective-C. MacRuby, a Ruby 1.9 implementation that sits directly on the Mac OS X core, gives Rubyists the potential to code Cocoa apps without sacrificing the language features they've come to depend on.

You should learn a programming language every year, as recommended by The Pragmatic Programmer. But if one per year is good, how about Seven Languages in Seven Weeks? In this book you'll get a hands-on tour of Clojure, Haskell, Io, Prolog, Scala, Erlang, and Ruby. Whether or not your favorite language is on that list, you'll broaden your perspective of programming by examining these languages side-by-side. You'll learn something new from each, and best of all, you'll learn how to learn a language quickly....

Clojure is a practical, general-purpose language that offers expressivity rivaling other dynamic languages like Ruby and Python, while seamlessly taking advantage of Java libraries, services, and all of the resources of the JVM ecosystem. This book helps you learn the fundamentals of Clojure with examples relating it to the languages you know already, in the domains and topics you work with every day. See how this JVM language can help eliminate unnecessary complexity from your programming practice and open up new options for solving the most challenging problems. ...

And then there was light – a lightweight database! How often have we all wanted some database that was "just a data store"? Sure, you can use it in many complex ways but in the end, it's just a plain simple data store. Welcome MongoDB! And then there was light – a lightweight language that was fun to program in. It supports all the constructs of a pure object-oriented language and is fun to program in. Welcome Ruby! Both MongoDB and Ruby are the fruits of people who wanted to simplify things in a complex world. Ruby, written by Yokihiro Matsumoto was made, picking the best...

In 2004, Ruby on Rails became public. The world was surprised by its productivity and by the magic of Ruby that enabled Ruby on Rails. Many people knew Ruby before Rails, but few realized the power of the language, especially metaprogramming. But Rails is not the first framework to realize the power of Ruby. dRuby came long before Rails. It uses metaprogramming features for distributed programming. Proxy objects “automagically” delegate method calls to remote objects. You don’t have to write interface definitions in XML or any IDL.

We’ve known about algorithms for millennia, but we’ve only been writing computer programs for a few decades. A big difference between the Euclidean or Eratosthenes age and ours is that since the middle of the twentieth century, we express the algorithms we conceive using formal languages: programming languages. Computer scientists are not the only ones who use formal languages. Optometrists, for example, prescribe eyeglasses using very technical expressions, such as “OD: -1.25 (-0.50) 180◦ OS: -1.00 (-0.25) 180◦”, in which the parentheses are essential.

Ruby is “a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.”1 It was released in 1995 by Yukihiro “Matz” Matsumoto. It is often described as either a very high-level language or a scripting language, depending on whom you ask. As such, it doesn’t require a programmer to specify the details of how the computer implements your decisions. Like other high-level languages, Ruby is often used in text-processing applications, including an increasing number of web applications.

Typical algorithms and data structures textbooks are seven or eight hundred pages long, include chapters about software engineering and the programming language used in the book, and include appendices with yet more information about the programming language. Often they include lengthy case studies with tens of pages of specifications and code. Frequently they are hardcover books printed in two colors; sometimes they have sidebars with various sorts of supplementary material.

As time has progressed, computers have made giant leaps in the area of processing power. This has brought about newer programming languages that are more abstracted from the underlying hardware. Popular programming languages of the modern era include C++, C#, Objective-C, Visual Basic, SQL, HTML with PHP, ActionScript, Perl, Java, JavaScript, Ruby, Python, Haskell and dozens more.[11] Although these high-level languages usually incur greater overhead, the increase in speed of modern computers has made the use of these languages much more practical than in the past.
