    tutorial confusion <<endl;

    in lesson 3, loops


    cout<<x; makes perfectly sense to my, but why adding <<endl, what does it change? it can't be a variable since it never gets defined.

    if it's something like endlOOP.. that makes no sense to me either since } ends the loop, in a further code there even is written x++; below it... anyway, i'm confused. about that little thing.

    end line This is just a slightly fancyer and cooler way of saying cout << x << '\n'. The cooler part is that it flushes the buffer. cout does not always write what you send to it right away. It tries to build up a bunch of things to send in one block.

    endl is end line, it does the same thing as /n.

    It also flushes the output buffer.
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah
