"C++17 In Detail" 是由 Bartłomiej Filipek 所著的一本书,专门针对C++17的新特性和其在实际编程中的应用进行了深入讲解。随着C++标准每三年更新一次,学习和掌握这些新功能变得尤为重要。这本书不仅列出了C++17的所有新增特性,如if constexpr、optional和variant等,还提供了丰富的实例来演示如何有效利用这些特性优化代码,例如升级enable_if、重构代码以及编写并行算法。作者强调了新特性的重要性,它们不仅在于了解它们本身,更在于如何通过它们直接表达编程意图,提高代码的清晰度、可读性和正确性。 书中特别关注了语言的清晰度,如严格的表达式评估顺序和对异常规范在类型系统中的处理。此外,书中还提到了编译器支持的变化,如动态内存分配对于过对齐数据的处理。对于那些使用现代C++编译器处理真实世界项目的程序员来说,C++17是当前工业界编写健壮生产代码的标准。通过深入理解和熟练运用C++17,可以提升日常编码效率,并减少维护和调试工作。 如果你是Bartek博客(bfilipek.com)的常客,那么你会喜欢这本书的娱乐性和知识性。即便你尚未接触过他的博客,也应该去阅读,因为这本书是对博客内容的延续,会带你领略C++17的精彩世界。这是一本适合想要深入学习C++17并将其应用于实践的开发者阅读的书籍,无论是初学者还是经验丰富的程序员都能从中受益匪浅。

Welcome to Beginning C++17. This is a revised and updated version of Ivor Horton’s original book called Beginning ANSI C++. The C++ language has been extended and improved considerably since then, so much so that it was no longer possible to squeeze detailed explanations of all of C++ into a single book. This tutorial will teach the essentials of the C++ language and Standard Library features, which will be more than enough for you to write your own C++ applications. With the knowledge from this book, you should have no difficulty in extending the depth and scope of your C++ expertise. We have assumed no prior programming knowledge. If you are keen to learn and have an aptitude for thinking logically, getting a grip on C++ will be easier than you might imagine. By developing C++ skills, you’ll be learning a language that is already used by millions and that provides the capability for application development in just about any context. C++ is very powerful. Arguably, it’s more powerful than most programming languages. So, yes, like with any powerful tool you can wield some considerable damage if you use it without proper training. We often compare C++ to a Swiss Army knife: age-old, trusted, incredibly versatile, yet potentially mind-boggling and full of pointy things that could really hurt you. Once someone clearly explains to you what all the different tools are meant for, however, and teaches you some elementary knife safety rules, then you’ll never have to look for another pocketknife again. C++ does not need to be dangerous or difficult at all either. C++ today is much more accessible than many people assume. The language has come a long way since its conception nearly 40 years ago. In essence, we have learned how to wield all its mighty blades and tools in the safest and most effective way possible. And, more importantly perhaps, the C++ language and its Standard Library have evolved accordingly to facilitate this. The past decade in particular has seen the ris
