C++ can not clear the screen, as indicated in the FAQ Victor pointed you to.
However, you can ask the OS to do it for you. The most common ways to do
this are 'system("cls"); ' in Windows and system("clear") ;' in Linux. The
system function is defined in <process.h>

Huh? C++ can do a lot of things using the OS specific libraries. Dont say
C++ cannot clear the screen. Instead, you should say standard C++ cannot
clear the screen.

But in all honesty, C++ cannot clear the screen. It's some OS-
specific library call that does that. Or sequence of characters
output to console or ... But it is not a language thing. And,
by the way, while there exist extensions to the language created
by some eager compiler vendors, there is only one C++ -- Standard.
That's what we mean when we say "C++ cannot do that". Another
example: can C++ read files? Yes. Can C++ read JPEG files? Yes.
Can C++ read and display JPEG files? NO. Displaying them is not
a language feature. C++ cannot do that. Not standard, not any
other C++. The same with clearing the screen.
Guiding others to a particular newsgroup is a voluntary thing. If
you stop me in the street and ask whether I could give you a lift
to a town a thousand kilometres away, I'll probably say "No, sorry,
I cannot do that", but I am not obligated to explain to you all
possible options you have or direct you to a bus station. It is
up to you to figure that out. (Of course it might be mighty kind
of me to point you to a bus stop, and I _probably_ would do that
if I knew where you were going -- The OP just asked whether there
was a way to clear the screen except outputting newline characters,
and there isn't). See the point?
Anyway...

I agree with you. But if you tell me that you cannot give me a lift to a
thown a thousand kilometers away doesnt mean that you should tell me that
there is no way I can go to that town. Thats what the other person did. He
said that C++ cannot... I am not saying that he or you HAVE to guide the OP
to an appropriate newsgroup, its voluntary ofcourse, but dont MISguide him
saying that it cannot be done. Get it?

And those OS-specific libraries cannot be used using C++. I get it now.

No. Using the same analogy, the other person told you that you
can't get to another town in Victor's car. He didn't say that
clearing of the screen cannot be done. He said that clearing of
the screen cannot be done with C++. Get it?

Do you understand the difference between "it cannot be done" and
"it cannot be done using C++ means"? Saying the latter does NOT
imply the former, and in no way is misguiding. Get it?

Yes. A couple of reasons actually. First, it has become an off-topic thread
and anyone who cares to read off-topic posts should probably take the
efforts to scroll down to the bottom. Second, I am too lazy.

I guarantee you that I can show you several systems where C++,
standard or not, cannot clear the screen. For the simple reason that
there IS NO SCREEN. One of the reasons C++ does not support a screen
is that it does not require one.

I am sorry, I had put my statement wrongly. But, since the OP asked about
clearing the screen, I assumed he had a screen (a computer monitor).
