If you need to know C++, look no further! This comprehensive guide has everything you need to master the modern C++23 language, from syntax fundamentals to advanced development concepts. Follow practical code examples as you learn object-oriented programming, work with standard library containers, program concurrent applications, and more. Don't just learn how to code-learn how to code better with expert tips and guidance on the rules of compact, secure, and efficient code.

In this book, you'll learn about:

a. Basic to Advanced Programming
Master C++ programming from the ground up. Learn how to code with building blocks such as comments, variables, and functions, and then walk through object-oriented programming. Graduate to advanced concepts, including pointers and templates.

b. The Standard Library
Dive into the C++ standard library, including an in-depth guide to containers: what they can do, what they can't do, and how to choose the right one for your scenario. Work with streams and files, explore unique syntax, and implement concurrency using threads.

c. Good Coding Practices
Write effective, sustainable code. Dedicated chapters provide guidelines, techniques, and tips for good coding. Put theory into practice with numerous sample programs that you can download to help jump-start your own projects.

Highlights include:

1. Language basics
2. Statements and expressions
3. Structures and classes
4. Object-oriented programming
5. Containers
6. Threading
7. Error handling
8. Testing
9. Pointers
10. Interface to C
11. Templates
12. Best practices

Learn to use the standard library and containers
