is iostream important

[Aerials]

how important exactly is it

[HarryW]

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.
