Data Structures and Algorithms with the C++ STL

This is the code repository for Data Structures and Algorithms with the C++ STL, published by Packt.

A guide for modern C++ practitioners

What is this book about?

While the Standard Template Library (STL) offers a rich set of tools for data structures and algorithms, navigating its intricacies can be daunting for intermediate C++ developers without expert guidance. This book offers a thorough exploration of the STL’s components, covering fundamental data structures, advanced algorithms, and concurrency features.

This book covers the following exciting features:

Streamline data handling using the std::vector
Master advanced usage of STL iterators
Optimize memory in STL containers
Implement custom STL allocators
Apply sorting and searching with STL algorithms
Craft STL-compatible custom types
Manage concurrency and ensure thread safety in STL
Harness the power of parallel algorithms in STL

Instructions and Navigations

All of the code is organized into folders.

The code will look like the following:

template <typename T,
 typename AllocatorPolicy = std::allocator<T>>
class CustomVector {
 // Implementation using AllocatorPolicy for memory
 // allocation
};

Following is what you need for this book: This book is for intermediate-level C++ developers looking to enhance their software development skills. Familiarity with basic C++ syntax and object-oriented programming (OOP) as well as some exposure to data structures and algorithms is assumed. Tailored to software engineers, computer science students, and hobbyist programmers, this book delves into C++ STL for practical application, performance enhancement, and efficient coding practices.

With the following software and hardware list you can run all code files present in the book (Chapter 1-22).

Page 14 (code block 2):

 #include <iostream>
 #include <vector>
 int main() {
   std::vector<int> numbers = {10, 20, 30, 40, 50};
   try {
     const auto secondElement = numbers.at(1);

  // This will throw an exception because there are only 5 elements.
  const auto outOfBoundsElement = numbers.at(10);

  std::cerr << "Error: " << e.what() << "\n";
