C++ in the wild: Which industries use C++?

C++ is a general-purpose programming language used for various applications, including operating systems, databases, browsers, machine learning tools, fintech and banking, game development, AR/VR, embedded systems, IoT devices, GUI-based apps, and cloud and distributed systems. The language's performance, portability, and low-level access make it suitable for resource-intensive or limited hardware applications. However, C++ also has security concerns, such as memory management mistakes, type safety issues, and potential vulnerabilities from open source software. To mitigate these risks, tools like Snyk can be used to detect vulnerabilities in open source dependencies. Overall, C++ is a popular choice for many industries due to its performance, flexibility, and versatility.
