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 Claims like "C++ is too hard to learn" or "C++ is obsolete" are often rooted in some truth, but they are outdated and fail to capture the language’s ongoing evolution and modern capabilities.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

The realm of free compilers

Two of the three major compilers today are developed and maintained in an open-source manner. This means that, in theory, anyone can contribute and provide useful new features to their compiler of choice. However, in practice, it means that there is a tiny core of professional programmers who have the necessary knowledge and dedication, and also the backing of a large corporation benefiting from the development of the aforementioned compiler working on it.

In no particular order, GCC and Clang (and MSVC, which we discussed in the previous section) are the most standard-compliant compilers as of 2024. This standard compliance, however, does not mean that these compilers don’t come with their own perks that a developer once thought would be a great idea to incorporate.

Let’s take, for example, the computed goto feature of GCC (and Clang too, of course; those two tend to go hand in hand). We all have learned in school that goto is just plain...
