Maximize Reward and Minimize Risk with Modern C++

Embracing Modern C++ Safely shows students how to make effective use of the new and enhanced language features of modern C++ without falling victim to potential pitfalls.

Based on their years of experience with large, mission-critical projects, four leading C++ authorities divide C++11/14 language features into three categories: Safe, Conditionally Safe, and Unsafe. Safe features offer compelling value, are easy to use productively, and are relatively difficult to misuse. Conditionally Safe features offer significant value but come with risks that require significant expertise and familiarity before use. Unsafe features have an especially poor risk/reward ratio, are easy to misuse, and are beneficial in only the most specialized circumstances.

This book distills the C++ community's years of experience applying C++11 and C++14 features and will help students make effective and safe design decisions that reflect real-world, economic engineering tradeoffs in large-scale, diverse software development environments. The authors use examples derived from real code bases to illustrate every finding objectively and to illuminate key issues. Each feature identifies the sound use cases, hidden pitfalls, and shortcomings of that language feature. After reading this book, students will:

  • Understand what each C++11/14 feature does and where it works best
  • Recognize how to work around show-stopping pitfalls and annoying corner cases
  • Know which features demand additional training, experience, and peer review
  • Gain insights for preparing coding standards and style guides that suit the needs of organizations
  • Be equipped to introduce modern C++ incrementally and judiciously into established code bases

Seasoned C++ developers, team leads, and technical managers who want to improve productivity, code quality, and maintainability will find the insights in this modular, meticulously organized reference indispensable.
