Rainer Grimm - C++ Core Guidelines Explained: Best Practices for Modern C++

Pearson is dedicated to creating bias-free content that reflects the diversity of all learners. We embrace the many dimensions of diversity, including but not limited to race, ethnicity, gender, socioeconomic status, ability, age, sexual orientation, and religious or political beliefs.

Education is a powerful force for equity and change in our world. It has the potential to deliver opportunities that improve lives and enable economic mobility. As we work with authors to create content for every product and service, we acknowledge our responsibility to demonstrate inclusivity and incorporate diverse scholarship so that everyone can achieve their potential through learning. As the worlds leading learning company, we have a duty to help drive change and live up to our purpose to help more people create a better life for themselves and to create a better world.

Our ambition is to purposefully contribute to a world where:

• Everyone has an equitable and lifelong opportunity to succeed through learning.

• Our educational products and services are inclusive and represent the rich diversity of learners.

• Our educational content accurately reflects the histories and experiences of the learners we serve.

• Our educational content prompts deeper discussions with learners and motivates them to expand their own learning (and worldview).

While we work hard to present unbiased content, we want to hear from you about any concerns or needs with this Pearson product so that we can investigate and address them.

• Please contact us with concerns about any potential bias at https://www.pearson.com/report-bias.xhtml.

C++ is a very rich, very expressive language with lots of features. It has to be because a successful general-purpose programming language must have more facilities than any one developer needs, and a living and evolving language will accumulate alternative idioms for expressing an idea. That can lead to choice overload. So, what does a developer choose for programming style and mastery? How does a developer avoid getting stuck with outdated and ineffective techniques and programming styles?

The C++ Core Guidelines (https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md) are an ongoing open-source project to address such issues by gathering widely recognized modern C++ best practices together in one place. The Core Guidelines rely on decades of experience and earlier sets of coding rules. They share a conceptual framework with C++ itself, with a focus on type safety, resource safety, and the elimination of avoidable complexities and inefficiencies. The Core Guidelines are organized to address known problem areas and partly phrased to enable enforcement by a static analyzer.

The Core Guidelines are organized as a reference work to make it easy to look up and share specific topics, not as a tutorial to be read sequentially to learn themes for using modern C++ well. We are therefore very pleased to see Rainer Grimm applying his teaching skills and industrial background to tackle the hard and necessary task of making the rules accessible to more people. We hope that you find learning the Core Guidelines stimulating and, especially, that applying them to your real-world problems will make your work significantly more effective and more enjoyable.
