My bad. Must have not seen that one
firedraco (6243)
Not a problem. ;)

It turns out most of the solutions dont work for me. And i want it to do something and that the other ones that might work is something i can not use. Because it will ruin what i need to do.

cout << string( 100, '\n' );
doesn't work for you?

It works but it makes the text look wierd :| like all the text is now on the bottom. I want it to stay on top :)

What OS are you using? Depending on what you are using there are different ways of putting the cursor at the top of the screen.

Windows XP

But that has nothing to do with it its that its not clearing its just making a bunch of empty lines :|

So basically it calls it has like its a mass info thing look of nothing

Try reading http://www.adrianxw.dk/SoftwareSite/Consoles/Consoles2.html. If you print enough blank lines, then put the cursor at the top left of the screen it will have the effect you want.

You could look into ncurses/pdcurses (windows version I think).
They have this neat function; clrscr() I think.

http://web.cs.mun.ca/~rod/ncurses/ncurses.html

Change any ncurses.h to curses.h and link with this ( http://gnuwin32.sourceforge.net/packages/pdcurses.htm ) and you're away.
