C++ is a powerful language. It gives developer nearly-full control of a computer, which is pretty powerful in the right developers’ hands. However, it is not the right hammer for all of the nails. The code tends to overly-complicate itself, the tooling is not easy to use, and it is easy to mess it up. Right quality of developers are hard to find, and this is becoming harder every day. So, in order to choose your nails, there is four for you.
Fintech and Banking Solutions
C++ is nice at number-crunching, it is verifiable by the source and the binary, and it is pretty-efficient in multi-threaded software. It also is proven to be concurrent. This makes it one of the best solutions for back-end or mainframe kind of software for fintech and banking systems. It is also available to satisfy financial industry regulatory requirements when needed.
Modern games require pretty high performances to render complex worlds. Also, they need to handle multiplayer networking problems. C++ is fully-pledged in low-level resource manipulation, enabling its developers to manipulate the hardware the game will run on.
It is also the best option for augmented or virtual reality solutions, since they both need hard rendering, but also they need lots of sensor data to be processed in real time.
Not to mention, lots of AAA games and AR&VR applications were on Unreal Engine, which is built on C++.
Distributed Systems or Cloud Solutions
Cloud computing systems should run close to the hardware. Thus, C++ is a nice candidate for cloud computation or storage solutions. C++ gives great performance due to multithreading, which will help for load-balancing and such. Also, as the silver lining, C++ code can be compiled for nearly every architecture around, and this means it is portable for different computers with different processors or such.
Embedded Systems and IoT Devices
Embedded systems are small devices with a low-power computer embedded in it. They include smart watches, medical devices and so. The devices are built with a specific set of hardware that should be optimized by C++’s low-level controls.
IoT devices are similar to embedded systems, but they also are connected to the Internet. And with less resources, connectivity may become an issue for these devices. They definitely need C++ to connect to themselves with limited resources.
