C++20 STL Cookbook

By: Bill Weinman

Overview of this book

Fast, efficient, and flexible, the C++ programming language has come a long way and is used in every area of the industry to solve many problems. The latest version C++20 will see programmers change the way they code as it brings a whole array of features enabling the quick deployment of applications. This book will get you up and running with using the STL in the best way possible. Beginning with new language features in C++20, this book will help you understand the language's mechanics and library features and offer insights into how they work. Unlike other books, the C++20 STL Cookbook takes an implementation-specific, problem-solution approach that will help you overcome hurdles quickly. You'll learn core STL concepts, such as containers, algorithms, utility classes, lambda expressions, iterators, and more, while working on real-world recipes. This book is a reference guide for using the C++ STL with its latest capabilities and exploring the cutting-edge features in functional programming and lambda expressions. By the end of the book C++20 book, you'll be able to leverage the latest C++ features and save time and effort while solving tasks elegantly using the STL.

Chapter 11: A Few More Ideas

We've learned some useful techniques in this book, including optional values, containers, iterators, algorithms, smart pointers, and more. We've seen examples of these concepts in use, and we've had the opportunity to experiment and apply them to some small projects. Let's now apply these techniques to a few more practical ideas.

In this chapter, we cover the following recipes:

  • Create a trie class for search suggestions
  • Calculate the error sum of two vectors
  • Build your own algorithm: split
  • Leverage existing algorithms: gather
  • Remove consecutive whitespace
  • Convert numbers to words
