## What are data structures and algorithms?

Data structures are ways of organizing and storing data in memory so that they can be accessed and manipulated easily. Some common examples of data structures are arrays, lists, stacks, queues, trees, graphs, hash tables, etc. Each data structure has its own advantages and disadvantages depending on the type of data and operations required.

Algorithms are step-by-step procedures for solving a specific problem or performing a certain task using data structures. Some common examples of algorithms are searching, sorting, encryption, compression, etc. Each algorithm has its own complexity and efficiency depending on the input size and the data structure used.

## Why learn data structures and algorithms in C?

C is one of the most widely used programming languages in the world. It is a low-level language that gives you direct access to memory management and hardware features. It is also a portable language that can run on different platforms and devices. Learning data structures and algorithms in C will help you understand how they work behind the scenes and how to optimize them for performance and memory usage.

However, learning data structures and algorithms in C also poses some challenges. C is not an object-oriented language, which means that it does not support features like classes, inheritance, polymorphism, etc. These features make it easier to design modular and reusable code that follows the principles of abstraction and encapsulation. To overcome this limitation, you need to learn how to implement object-oriented concepts using C syntax and conventions.

## How to get the book by Adam Drozdek?

The book by Adam Drozdek is one of the most comprehensive and up-to-date books on data structures and algorithms in C++. It covers both the theoretical and practical aspects of the topics, giving equal weight to the analysis and implementation of data structures and algorithms. It also provides numerous examples, exercises, case studies and code snippets in C++ to illustrate the concepts and applications.

The book is available in both print and digital formats. You can buy the print version from online or offline bookstores, or you can download the digital version for free from various websites. One of the websites that offers the PDF version of the book for free is this one. However, we recommend that you buy the original book if you can afford it, as it will support the author and the publisher.

## What are the main topics covered in the book?

The book consists of 18 chapters, each covering a different topic related to data structures and algorithms. Here is a brief overview of each chapter:

### Object-oriented programming using C++
