    When I try to use it, I get an error message saying undeclared indentifier on Visiual C++. Do I have to include any header files?

    >Does anyone know how I can clear the screen of my program
    Why do you need to clear the screen? In my experience, such functionality is almost never needed. Then there's the portability problem as well. I would wager that you want to clear the screen so that you can print a pretty little menu, am I correct?

    >without just putting a bunch of endl; or \n; ??
    Thats' basically what you end up doing no matter how much abstraction you put around it.
    My best code is written with the delete key.

    It's part of an assignment. We have to make a version of the Game "Connect Four" and we're asked to clear the screen so that we can redraw the board.

    And I bet you still didn't read the FAQ, did you?

    Hope is the first step on the road to disappointment.

    I detect a lot of n00b hate here. Calm down before mannyginda lets off one of those n00b tirades. They are all too common at this time of year.

    No need to calm down; it's in the FAQ. Click that. It's a link. To the answer. For your question. Merry Christmas. While you're there, read the rest of the articles.
    Away.

    Take the low road and keep it simple.
    Code:
    void clearscr ( void )
    {
      for ( int i = 0; i < 50; i++ ) // 50 is arbitrary
        cout<<'\n';
      cout<<flush;
    }

    >function= system("cls")
    slow + nonportable = not recommended

    Any program that needs to clear the screen (or thinks it needs to clear the screen) is going to be doing it a lot. Calling speed intensive functions like system frequently is going to slow down the program a great deal. The nonportable part isn't as important since the OP is probably working with Windows exclusively, but it's still a bad habit to get into.

    In general I recommend against using system except when it's really necessary, even if the alternative solution is platform or compiler dependent. Of course, the point is moot if the OP actually looks at the FAQ and uses the function defined there.

    }
    is there a better way than this? (my compiler doesn't have clrscr())
    and what does flush do?
