Can c++ only develop a social media app

Answer 1

I am not sure if it is impossible# but it would be extremly unpractical. Facebook, Google, Snapchat - all of.tjese are made in a few languages, because if you connect them together in the right way, you will have much easier job and you can achieve better performance.
Truth is, that C++ is often the main language in such applications, but it is never alone.

Answer 2

Jan Štěch together with JAVA PHP and ERLANG prolly
