In your opinion, why is C++ the most common programming language? [Aside from it is used in making apps... etc.]

Question

C++ Question!

Answer 1

because of its support for low-level programming. This is the reason that most os and drivers, etc are made using c or c++.Also because its older more people know it, including teachers & institutions who teach this to newer generation.
But wait i don't think that its the most common programming language, languages like python and even java along with newer dynamic languages like go, haskell, r, etc are changing things.

Answer 2

because it is an "all around" programming language. you can do the things which you can do with other (also older) programming languages + object oriented programming.
