Book description

Test your C++ programming skills by solving real-world programming problems covered in the book

Key Features

  • [*] Solve a variety of real-world programming and logic problems by leveraging the power of C++17
  • [*] Test your skills in using language features, algorithms, data structures, design patterns, and more
  • [*] Explore areas such as cryptography, communication, and image handling in C++

Book Description

C++ is one of the most widely-used programming languages and has applications in a variety of fields, such as gaming, GUI programming, and operating systems, to name a few. Through the years, C++ has evolved into (and remains) one of the top choices for software developers worldwide. This book will show you some notable C++ features and how to implement them to meet your application needs. Each problem is unique and doesn't just test your knowledge of the language; it tests your ability to think out of the box and come up with the best solutions. With varying levels of difficulty, you'll be faced with a wide variety of challenges. And in case you're stumped, you don't have to worry: we've got the best solutions to the problems in the book. So are you up for the challenge?

What you will learn

  • [*] Serialize and deserialize JSON and XML data
  • [*] Perform encryption and signing to facilitate secure communication between parties
  • [*] Embed and use SQLite databases in your applications
  • [*] Use threads and asynchronous functions to implement generic purpose parallel algorithms
  • [*] Compress and decompress files to/from a ZIP archive
  • [*] Implement data structures such as circular buffer and priority queue
  • [*] Implement general purpose algorithms as well as algorithms that solve specific problems
  • [*] Create client-server applications that communicate over TCP/IP
  • [*] Consume HTTP REST services
  • [*] Use design patterns to solve real-world problems

Who this book is for

This book will appeal to C++ developers of all levels. There's a challenge inside for everyone.
