X++ is where the name C++ came from?

Question

this language is called C++. is it because of this common operator?

Answer 1

If I understood your question correctly, then yes. C++ should indicate the next iteration of the programming language C.

Answer 2

C++ got it's name from his ancestor C. Bjarne Stroustrup created an object oriented language out of it , so C++ gains everything thats in C (by the way is inheritance one of the things that are new). And because it's a "better" (actually just different) C, he called it C++. And the unary operator (++/--) was in C first, so you may use it there.
