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 Claims like "C++ is too hard to learn" or "C++ is obsolete" are often rooted in some truth, but they are outdated and fail to capture the language’s ongoing evolution and modern capabilities.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

Compatibility

Let’s assume that you find a very promising library and decide to add it to your project. Does it work? How well will it work?

Here’s where the fragmentation of C++ shows its ugly side. The chance of any of the following undesirable things to happen is non-zero:

  • The library uses a newer C++ version than your code and you can’t compile it
  • The library uses an older C++ version than your code
  • You get a lot of warnings for different reasons
  • The library compiles well with your version of C++, but its interface uses older constructs
  • The library doesn’t work on all platforms your project targets
  • The library is incompatible with your compiler
  • The library is incompatible with your compilation process
  • The library is compatible with all platforms your project targets, but it has different behavior or performance issues or bugs on specific platforms

I hope you never encounter any of the preceding problems....
