I searched it online but understood nothing, haven't looked at cppreference though, will give it a try. Thanks mate

do you know what cout is?

charred monolith
#

I read through it, still, what is a stream I cannot understand

rain galleon
#

well cout is a type of ostream

charred monolith
#

That's weird, I can't see the relation

#

Doesn't cout just print out stuff in the terminal?

rain galleon
charred monolith

Aalright just a sec

#

that's not the main way I would describe them, but, sure?

#

lots of things can be variables, so that doesn't say much

charred monolith
#

But what type of data do they hold, can one stream hold and integer and a character?

#

And is that definition not used for arrays also

#

Or if I had to sum up my question, what is the difference between a stream and an array?

rain galleon
#

I am feeling like it's not likely possible for you have to actually read that whole chapter in the time since I posted the link

#

maybe read it first

charred monolith
#

Alright

#

I read the definition

#

And had a lot of questions

rain galleon
#

well then you may need to start over reading from chapter 1

#

that's chapter 23

charred monolith
#

But I can write programs in cpp, I should know all the basics and a bit more

#

I will scan through the definition again a couple of times, see if I can make sense of it

#

Alright, so from what I can see the difference is that streams can hold on to data while the device is getting ready to accept it

#

How true is that?

@charred monolith Has your question been resolved? If so, run !solved :)

rain galleon
#

it's still not how I would describe a stream

#

streams are basically for io

#

hence the title of chapter 23

charred monolith
#

I read through it

rain galleon
charred monolith
#

But they are what

#

A function? A variable?

rain galleon
#

they are classes

#

as such yes they have functions

#

as such yes you can make variables out of them

#

like most classes

charred monolith
#

So ostream and istream are classes?

#

Or streams are classes

#

Or are istream and ostream streams

rain galleon
#

yes, yes and yes, respectively

charred monolith
#

Alright thanks, I'll keep reading
