Debunking C++ Myths

Debunking C++ Myths

By: Alexandru Bolboacă, Ferenc-Lajos Deák

Overview of this book

Think you know C++? Think again. For decades, C++ has been clouded by myths and misunderstandings—from its early design decisions to misconceptions that still linger today. Claims like "C++ is too hard to learn" or "C++ is obsolete" are often rooted in some truth, but they are outdated and fail to capture the language’s ongoing evolution and modern capabilities. Written by industry veterans with over 40 years of combined experience, this book uncovers the myths, exploring their origins and relevance in the context of today’s C++ landscape. It equips you with a deeper understanding of advanced features and best practices to elevate your projects. Each chapter tackles a specific misconception, shedding light on C++'s modern features, such as smart pointers, lambdas, and concurrency. You’ll learn practical strategies to navigate common challenges like code portability and compiler compatibility, as well as how to incorporate modern best practices into your C++ codebase to optimize performance and future-proof your projects. By the end of this book, you’ll have a comprehensive understanding of C++'s evolution, equipping you to make informed decisions and harness its powerful features to enhance your skills, coding practices, and projects.

Chapter done – turn the pages and see you in the next one.

However, this statement isn’t true. I wrote void main(void) just to wake your curiosity and put you in a state of alertness. At this point in their career, all C++ programmers should know that void main(void) is as far as standard C++ as Point Nemo is from the closest piece of dry land.

Oh – you’re still here! This means that you must have read the fine print. Excellent – we programmers should always pay attention to the finer details, such as how our application is loaded and executed in memory by the underlying operating system.

Since we live in a free world, we have the option to choose from several operating...
