Overview of this book

C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. The latest versions of C++ have seen programmers change the way they code, giving up on the old-fashioned C-style programming and adopting modern C++ instead. Beginning with the modern language features, each recipe addresses a specific problem, with a discussion that explains the solution and offers insight into how it works. You will learn major concepts about the core programming language as well as common tasks faced while building a wide variety of software. You will learn about concepts such as concurrency, performance, meta-programming, lambda expressions, regular expressions, testing, and many more in the form of recipes. These recipes will ensure you can make your applications robust and fast. By the end of the book, you will understand the newer aspects of C++11/14/17 and will be able to overcome tasks that are time-consuming or would break your stride while developing.

Writing your own random access iterator


In the first chapter, we saw how we can enable range-based for loops for custom types by implementing iterators and free begin() and end() functions to return iterators to the first and one-past-the-last element of the custom range. You might have noticed that the minimal iterator implementation that we provided in that recipe does not meet the requirements for a standard iterator because it cannot be copy constructible or assigned and cannot be incremented. In this recipe, we will build upon that example and show how to create a random access iterator that meets all requirements.

Getting ready

For this recipe, you should know the types of iterators the standard defines and how they are different. A good overview of their requirements is available at http://www.cplusplus.com/reference/iterator/.

To exemplify how to write a random access iterator, we will consider a variant of the dummy_array class used in the Enabling range-based for loops for custom...
