C++ Hello World Error

Question

As one can see, I am just starting out with C++ and just began my hello world program.

    #include <iostream>
using namespace std;

int main() {
    cout << "Hello, World!" << end1;
    cout << "Hooray!" << end1;

    system("PAUSE");
    return 0;
}

But for some reason, unknown to me, I am getting an error on both of the cout lines, saying end1 was undeclared! How do I fix this?

Also, get rid of the silly and dangerous [`system("PAUSE");`](http://www.gidnetwork.com/b-61.html). — David Schwartz, Feb 25 '12 at 23:44
How is it dangerous? Just wondering, and trying to learn more! — Billjk, Feb 25 '12 at 23:53
It's dangerous because you don't know what `pause` is supposed to do. In Windows it works as wonders, but in Linux it's not defined and could be defined by someone else. I use it anyway for simple test programs because it does what it needs to in Windows and just gets ignored in Linux. — Mysticial, Feb 26 '12 at 00:09
Using system just for pausing? It is absurd! Use other functions like `getch`, `_getch`, `getchar`, `cin.getline`, or event `scanf` to wait for keyboard input! But in reality, you shouldn't use any of them. The program is finished, just leave it. — Ajay, Feb 26 '12 at 09:37
Note that in C++ (and recent versions of C), it isn't necessary for `main` to `return 0`, as discussed [in this question](http://stackoverflow.com/questions/204476/what-should-main-return-in-c-c) - zero is returned by default. — James, Feb 27 '12 at 13:33

end1

should be:

endl

You used a 1 (the number) instead of l (the letter).

Thanks, the book was very unclear and the typeface makes them look exactly the same! Stupid me! – Billjk Feb 25 '12 at 23:43
I thought he was using a capital-I (eye). – Kerrek SB Feb 25 '12 at 23:47

It should be endl (end line), not end1 (end one?):

cout << "Hello, World!" << endl;
cout << "Hooray!" << endl;

endl represent end line, it is not end1.

You have a typo. Try endl instead of end1.

You should write endl instead of end1 (So make the one to a small "L")

replace end1 by endl and it'll work just fine! :)

Any particular reason why you answered this almost a year after the accepted answer which states exactly the same? – Bart Jan 12 '13 at 14:01

To avoid typos like the one you experienced, instead of using "endl", you can use 'new line' by inserting '/n' inside the quote.

Example:

cout << " Hi, this is how you do it /n";

You only need to replace your

     end1

with

    endl

Thus you have a syntax error that you need to fix by replacing the one('1') with an 'l', thereby fixing your program. It should compile and run successfully now.
