Look up the Sleep function to use as a delay for the message. To clear the screan, you can either use the "system("cls"), or better, do it manually:
C++ Syntax (Toggle Plain Text) 
  1. void Clear() {
  2.   DWORD n;
  3.   DWORD size;
  4.   COORD coord = {0};
  5.   CONSOLE_SCREEN_BUFFER_INFO csbi;
  6.  
  7.   HANDLE h = GetStdHandle ( STD_OUTPUT_HANDLE );
  8.  
  9.   GetConsoleScreenBufferInfo ( h, &csbi );
  10.  
  11.   size = csbi.dwSize.X * csbi.dwSize.Y;
  12.  
  13.   FillConsoleOutputCharacter ( h, TEXT ( ' ' ), size, coord, &n );
  14.   GetConsoleScreenBufferInfo ( h, &csbi );
  15.   FillConsoleOutputAttribute ( h, csbi.wAttributes, size, coord, &n );
  16.  
  17.   SetConsoleCursorPosition ( h, coord );
  18. }

ok, the first thing works, e.g.

C++ Syntax (Toggle Plain Text) 
  1. for(int i=0; i<10; i++) {
  2.    cout << i; 
  3.    sleep(3);
  4.    system("clear");
  5. }

but have no understanding on your second soluction. Is there a lib that should i use;

thanks for your reply

That is a windows only solution to clearing the screen, if you're using linux, you should either use system("clear") or use a portable library like ncurses.

Using system() commands is not a good idea, and windows specific functions are not a great solution either. You can use Clock() instead of sleep. Also, check out these special control characters as a way of clearing the screen.
