Clearing the sreen

I am programming C++ Source file and I want to know how to clear all the text from the screen before I cout anything else.  I searched through help and didn't find anything.  There has to be some command that will do this.  (Please include any header files that I need for that command.)  What I'm looking for is a simple command like CLS in DOS.
Thanks in advance.

#include <conio.h>

//The function you are looking for is

clrscr();

conio.h and clrscr() are not part of the standard C++ library.  Some implimentations may provide them some might not.  MS VC++, for example, does not.  In fact, standard C++ does not provide ANY way to clear the screen--because it doesn't necessarily run on a screen.   Thus you will have to use some sort of implimentation--specific solution.  (like conio.)  Thus if conio isn't available, we need to know what OS you are developing for and what compiler you are using.

nietod, he/she is talking about DOS not windows programming, thus the person can use conio without problems... If it is not on a Unix system, then conio.h can be used, and most of the DOS compilers provide it nowadays...

Maybe, but how can you tell for sure?

nietodCommented:
I intepret that to mean that he/she is looking for a command that works like the CLS does in DOS.  i.e simple command like [CLS in DOS].  Not as [simple command like CLS] in DOS.  Well, we'll see.

clrscr() does exactly what CLS does in DOS....you could also do this...

system("CLS");

but it doesn't always work properly...

you can write your own clrscr() routine for DOS using asseembler..the address to text mode is 0xB000

Let me clarify. I have Microsoft Visual C++ 5.0, running on Windows 95.  I am in a C++ class and right now we are not doing any Windows development.  All of the programs that we are doing are programmed using C++ source files that send output to a DOS window.  The system("CLS"); does work for what I am doing but the clrscr() gives the error undeclared variable.  viktornet, since you gave the answer that helped me, post the system("CLS"); as the answer and I'll give you the points.

As I said, not a DOS program.  I think the proper way to handle the screen in this case would be to use the WIN32 console functions.
