Is there any library function in C++ which could clear the run screen?

if you are talking about plain old c++ programming, I guess the conio.h has a funcition to clear the screen;





#include %26lt;iostream.h%26gt;


#include %26lt;conio.h%26gt;





void main()


{


clrscr();





}





i guess this works.

Tech Tips on Windows Keyboard Shortcuts for V6.0, and updated with all NEW shortcuts for Internet Explorer v7.0.





Borrowing from Firefox and other browsers, IE7 now features tabbed-browsing. With tabbed-browsing you can, among other things:





Use one Internet Explorer window to view all your web pages.


Open links in a background tab while viewing the page you're on.


Save and open multiple web pages at once by using favorites


and home page tabs.





Most people think they know the ins and outs of using their favorite software (and maybe they do), but there are hundreds of little shortcuts that can be used to make common tasks even easier. This Tech Tip is going to follow a different format than the norm and will list a few dozen of these hot keys that can be used to make working in Microsoft Windows even easier.

Final Words:


Windows hot keys are all intended to provide some sort of convenient alternative to common tasks, and whether specific combinations do so is up to the individual to decide. Some are simple time-saving motions, while others are complex maneuvers in finger gymnastics. There are dozens of other common Windows shortcuts (and even more related to specific software titles), and memorizing just a few of the more basic ones may be worth the time-savings they can afford you.





Good luck and we hope this will help you now as well as in the futire.
