C++ is a cross-platform language that can be used to create high-performance applications. C++ was developed by Bjarne Stroustrup, as an extension to the C language. C++ gives programmers a high level of control over system resources and memory. The main benefits of C++ are great performance and pace. It can also optimize large quantities of data quickly. That is why in broad, stable systems such as servers, where data processing is essential, it is most frequently applied. Moreover, its performance decreases the use of resources, which makes it a great mobile language. Some of the tech giants of all time are actually focused on C++. In the case of Microsoft, Oracle, Mozilla, Opera, PayPal, Evernote and Linkedin, this is the main technology. And the code is partially used by Amazon, Facebook, SAP, and Adobe.
