"\n" VS <<endl;

newbie alert.

/n is the same thing as endl he was aksing a prefrence the onyl differ is that you put /n inside the quotes endl is a seperate thing

/n example->

cout << "hello mom /n";
cout << "hello dad";
endl example->

cout << "hello mom" << endl;
cout << "hello dad";
the end resualt sshould be the same

No, as was stated before:

endl != \n
endl == \n + Flush

yah, whos the newb now punk ;)

<<endl;
simply cause i get lazy and its easier for this ol' fart to type that than other.
PEACE OUT!

:eek: :eek: :eek: :eek: :eek: :eek: ah well as someone with tons of brain power once said "learn something new a day"

lol if they had tons of brain power, they might have used a lil grammar and said "Learn something new every day"

i use newl - which simply returns '\n'

I read some performance issues on gcc2.95
in which '\n' was 60 times faster than endl - so I thought, why use endl??

a flush is made when the buffer is full - in most cases that's enough.

Only sometime (if I write to files) it is important to flush, because the program may crash and then the file would be empty...

I don't think you can say which is better because they are different.
Simply if you need to flush the buffer use endl, if you don't use '\n'.
it's that simple.

I have never really had much of a need to flush the buffer, so I just use them like this:

If it is a string, use \n, if it is after a variable, use endl.

Ex:

cout << "Hello, World! \n";

cout << myVar << endl;

Even though endl flushes the buffer, that is not taught in schools. The only thing that is taught in schools is that it goes to the next line, and so that is what people use it for. That is what I have always used it for, and so that's how I use \n and endl.

but..... I thought if you wanted to flush something (which solves all IO problems) you use fflush(stdin); Am I mistaken?


:D :D :D

i'll use endl then...

btw, newb alert yourself :P

All this discussion and noone has mentioned that stdout is unbuffered, hence no need for endl unless couting to a file, no?

but how will you know if you're outputting to a file or to a screen or whatever? all you know is that it's stdout.

Well, obviously. But in most cases, stout is directed to a terminal, and anyway, if otherwise, the programmer would know in advance (hopefully!).

when i use C++ Ostreams which is very rare i use 'endl', other wise i use '\n'.

>All this discussion and noone has mentioned that stdout is unbuffered

since when? i think this is imp dependant.
