Does anybody know how to clear the screen in text mode and return the position of the output to the top using cout and cin?

Depends on what compiler you''re using...I know Borland C++ has a function called clrscr() that''s in conio.h...but I don''t think VC++ does...there''s probably other ways, but I don''t know them.

Visual c++ uses

system("cls");

instead.

If you are using a dos compiler like borland c++, try using

clrscr();

and then

gotoxy(1,1); (to return to the top of the screen)

I think these functions are in conio.h

Why is system( "cls" ); so slow? It takes about a second to clear the screen?

system("cls") is something like running command.com then run cls. that''s why it is slow!


For vc++, try searching funtions in msdn like: SetConsoleTextAttribute, WriteConsole and alikes... i think they have clear screen too. Click the "group" button.
