Overview of this book

C++ has come a long way to be one of the most widely used general-purpose languages that is fast, efficient, and high-performance at its core. The updated second edition of Modern C++ Programming Cookbook addresses the latest features of C++20, such as modules, concepts, coroutines, and the many additions to the standard library, including ranges and text formatting. The book is organized in the form of practical recipes covering a wide range of problems faced by modern developers. The book also delves into the details of all the core concepts in modern C++ programming, such as functions and classes, iterators and algorithms, streams and the file system, threading and concurrency, smart pointers and move semantics, and many others. It goes into the performance aspects of programming in depth, teaching developers how to write fast and lean code with the help of best practices. Furthermore, the book explores useful patterns and delves into the implementation of many idioms, including pimpl, named parameter, and attorney-client, teaching techniques such as avoiding repetition with the factory pattern. There is also a chapter dedicated to unit testing, where you are introduced to three of the most widely used libraries for C++: Boost.Test, Google Test, and Catch2. By the end of the book, you will be able to effectively leverage the features and techniques of C++11/14/17/20 programming to enhance the performance, scalability, and efficiency of your applications.

Initializing a range

In the previous recipes, we explored the general standard algorithms for searching in a range and sorting a range. The algorithms library provides many other general algorithms, and among them are several that are intended for filling a range with values. In this recipe, you will learn what these algorithms are and how they should be used.

Getting ready

All the examples in this recipe use std::vector. However, like all the general algorithms, the ones we will see in this recipe take iterators to define the bounds of a range and can therefore be used with any standard container, arrays, or custom types representing a sequence that have forward iterators defined.

Except for std::iota(), which is available in the <numeric> header, all the other algorithms are found in the <algorithm> header.

How to do it...

To assign values to a range, use any of the following standard algorithms:

  • std::fill() to assign a value to all...
