endl not working for me!

[Dazzer]

********NOOB ALERT!********

Howdy folks, just a few days into my C++ journey!

I don't seem able to add line breaks, anyone know what i'm doing wrong?!

#include "stdafx.h"
 
 
#include <iostream>
int main()
{
    int x;
    x = 8;
    std::cout << x << endl;
        return 0; 
}

std::endl

Please show me the entire code as it needs to be!........ thanks!

Learncpp.com does it like this:

std::cout << x << endl;

??

Yes i read it, i tried it, it didn't work, probably because my whole code wasn't correct.

Remember, i'm a beginner and this is the beginners forum! :)

This is what i did:

#include "stdafx.h"


#include <iostream>
int main()
{
	int x;
	x = 8;
	std::endl << x;
		return 0; 
}

#include "stdafx.h"
 
 
#include <iostream>
int main()
{
    int x;
    x = 8;
    std::cout << x << std::endl;
        return 0; 
}

Great, thank you muchos, i guess it's time to read the "endl, the std " page on Learncpp.com!

Still curious why std::cout << x << endl; as shown on Learncpp.com didn't work, see here:

Because endl is defined within the namespace std. This means to the compiler, endl and std::endl are completely different things. Basically, all standard library things need to be prefixed with std:: because they often have names that you might want to use for your own functions (such as begin and end) and the std:: allows the compiler to recognise that the standard library endl is what you are looking for.

Notice that you are not given a complete program, only small snippet. There wass something allowing std::endl be found by unqualified lookup.

Thanks for the replys / information, this is gonna be a long road but i feel i've now made a start!
