Clearing the screen

[piked]

Hello.

Was just wondering if there's a C function to clear the screen, in dos.. without pumping it full of newlines.. the equivalent of CLS, essentially.

Thanks.

u can use the function

clrscr()

to clear the screen. in case u want to set the background to say blue after the screen is cleared, then use the following commands

textbackground(BLUE);
clrscr();

pl. note the correct header files are required for using this command.


also u can clear a window portion from the screen, the syntax is

window(tcol, trow, bcol, brow);


where tcol and trow represent top column and row and bcol and brow represents bottom column and row.


textbackground(BLUE);
clrscr();
textbackground(RED);
window(20, 10, 50, 20);
clrscr();
window(1,1,80,25);

the above commands first clears the screen and sets the screen color to blue, next creates a window from 10th row 20th column to 20th row 50th column with red background.

try out and do get back to this forum with your comments.

If you work on MS-DOS, it will be simple.
Just include the header file conio.h, and call the clrscr() function. Just like icici said.
But if you program in Unix/Linux, there's no conio.h file in there. So you gotta do it with printf() function (I think there's other way too). Sorry I forgot the code (but you can still look for it, just run the KDevelop if you're using Red Hat, and try to look for it in Help).

This also works:

#include<stdlib.h>
....
system(&quot;cls&quot;
