how important exactly is it
What a question.
What are you getting at?
iostream is what it is: a standard C++ library of stream-based input and output classes/methods. There's really not much else to say about it.
It's important for input and output, in a standardised, steam-based way. Which is pretty obvious really.
I meant does the library include any commonly used classes
I just started C++ geez
You will need to use it in almost any consol program, but it is not essential to C++. you could write a replacement for it if you wanted.
Sorry, I didn't mean to sound critical. It's just a strange question.
It is used a lot for input/output involving files, consoles, the standard input, output and error streams (stdin, stdout, stderr) and any other custom stream-like class you might want to create for your own purposes.
At a basic level, for learning C++ with console apps, you will use it a lot.
