Index....429

If you want to take advantage of the real power of Boost and C++ and avoid the confusion about which library to use in which situation, then this book is for you.

Beginning with the basics of Boost C++, you will move on to learn how the Boost libraries simplify application development. You will learn to convert data, such as string to numbers, numbers to string, numbers to numbers, and more. Managing resources will become a piece of cake. You'll see what kind of work can be done at compile time and what Boost containers can do. You will learn everything for the development of high-quality, fast, and portable applications. Write a program once, and then you can use it on Linux, Windows, macOS, and Android operating systems. From manipulating images to graphs, directories, timers, files, and networking, everyone will find an interesting topic.

Note that the knowledge from this book won't get outdated, as more and more Boost libraries become part of the C++ Standard.

Who this book is for

This book is for developers looking to improve their knowledge of Boost and who would like to simplify their application development processes. Prior C++ knowledge and basic knowledge of the standard library is assumed.
