What Is ++ Stands In C++?

++ means advancement in language. C++ is advanced than C as JAVA is advanced than C++

It doesn't stand for anything. In C, the operator ++ means increment, so

int i = 0;
i++;
printf("%d",i);

would print 1. So in the name of the language, it's something of a joke, and implies that C++ is an incremental improvement to C.

Previously C was developed. But After C is developed or modified to more advance such as object oriented language which have many more Facility then C.
So A newly developed language is called C. For it is developed from it.
Shortly, ++ Stands for increment in C++.

And
if we write
int i=1;
i++;

in c++ the value of i is increased to 2. That means it stands for increment.
