C++ here is some different from my school course

Question

here #include <iostream> and in my school book it's #include <upstream. h> I am totally confused

Answer 1

I believe 'upstream.h' is a typo of 'iostream.h', which in that case, belongs to pre-standard C++. You're from India, (and as has been asked by a lot of Indian students because their schools still teach obsolete stuff like TCC) this seems to be the case. I recommend studying standard C++ alongside your academic courses for your own benefit.
