Sustainable C++

Write faster, cleaner, and more sustainable software with modern C++. This book offers practical techniques that combine contemporary language features with real-world strategies to improve both performance and energy use. You’ll explore capabilities from C++17 through C++26 and learn how they can support substantial carbon reduction in systems ranging from IoT and cloud platforms to embedded devices and high-performance computing. Along the way, you’ll examine compiler optimizations, data-layout choices, and profiling workflows that expose where software wastes energy, and how to fix it. This book approaches green computing as an environmental priority that begins with the everyday programming decisions shaping a system’s energy footprint. By the end, you’ll understand how to make design choices that reduce power consumption, improve memory behavior, and support environmentally responsible software across modern applications. What You Will Learn: Integrate modern C++ features with green-computing principles Apply the performance–energy–memory triad to guide design decisions Leverage modern C++ language standards to build sustainable software Use sustainability metrics and coding practices to reduce energy and resource consumption Who This Book is for: Intermediate C++ developers who are familiar with modern C++ fundamentals and wish to deepen their understanding of performance-, energy-, and sustainability-oriented software design, as they progress toward advanced and research-level practices.
