Do you know why sharp is added to the end of programming languages? Like c sharp and f sharp?
There was (and still is) a language called C. Then C++ was invented. And then C#, maybe because # looks kinda like 4 pluses.
There is also another programming paradigm, called functional programming. F# is a functional programming language and runs on the same platform as C# (that platform is called .NET). That's why they named it F#.
Actually, I don't even know if it is pronounced c sharp or f sharp. I just assumed it was the same as music.
++ is the increment operator in C, which increases a value by 1. C++ was intended to be an improvement on C, and so it's saying that C++ is C incremented. C# is C++ ++ or C++ incremented. It's just a bunch of programmer jokes. There isn't a C+ afaik.
