C++ is a general-purpose computer programming language developed as an extension to C. C++ is extensively used in the field of web and game development and machine learning, data mining, and various other applications. The beauty of C++ is that, even amidst the prevalence of other programming languages like Python and Java, it still retains its value. You will still find many top organisations like Microsoft, Amazon, and Google hunting for expert C++ developers. It is one of the oldest yet still among the most popular programming languages in the history of computer science.
