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 Claims like "C++ is too hard to learn" or "C++ is obsolete" are often rooted in some truth, but they are outdated and fail to capture the language’s ongoing evolution and modern capabilities.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.

When the header is not even C++

The long list of standard-non-compliant-but-still-working-and-useful features does not end with the preceding examples. However, if we had only focused our attention on those, we could still have filled several books with them. Sadly, for the moment, we have only dedicated one chapter to this topic, so let’s move our attention to somewhat more exotic features.

Qt has been the de-facto cross-platform programming framework for GUI applications (but not only) for quite some time. Throughout its fateful history, while exchanging owners several times since its inception in 1994, the Qt framework has evolved significantly, with each release giving a new set of features to the C++ (but not only) programming community. However, one feature has remained more or less the same: the signal/slot implementation and the Meta Object Compiler (MOC). The pillar of the framework, the MOC makes it possible to connect events from components (i.e., signals) to receivers...
