Writing Efficient C++ Code

The article argues that C++ remains strategically important for performance-critical software because it gives teams direct control over memory, runtime behavior, and hardware utilization—capabilities that matter for games, real-time systems, mobile devices, and long-lived software deployed at scale. Its core implication for CIOs is that code efficiency is not just a developer concern but a business issue that affects infrastructure cost, battery life, user experience, and scalability; the article recommends Data-Oriented Design to improve cache locality, simplify parallelization, and better exploit modern hardware.
